Are they good or bad (I assume bad)
But it is a lot of head for the money, if they work :- )

Don't do it! There are too many reasonably priced domestic castings of far greater quality.Examples are dart shp, pro-filer ,brodix etc...
The cost of shipping a set back to the states would make the afr line affordable as well.Fwiw the afr and pro-filer heads seem to be the best performers out of the box right now.Chad Speier would be your man on the pro-filer.I have a dart shp 400 build that is just about complete and I hope to start it for the first time next week.This build is using a 210 pro-filer head.Good luck shopping

 

I completely agree. If your budget doesnt allow then hold off and save up, heads are were power is built and in my opinion are not the place to skimp.

 

Don't do it.

 

:- )
I will be "scary" the day China gets a good quality.
It is a big head, for small money, and if you can grind the seats, and give them some love, don't you think it would work??

It is not for me, I like AFR.

 

Yes they are "cheap"

I've tried the China head thinking I could save a few bucks, these are the issues my set had. I bought them bare thinking I could get the machine work done right with quality US parts. The installed valve guides were shaped like footballs (underside at the tops and bottoms but oversize in the middle section) throats were larger than the valves. Combustion chambers larger than the bores. Valve seat angles cut too deep in the chamber. Could the head have worked. Yes, after the cost of good valvetrain components the machine work and the bare castings the cost would have been more than a set of dart shp's out of the box.

 

Good info, thanks.

I wish this Chinese junk would just go away, probably been 10 years now and still going strong for people who don't know and want to save a few bucks it ends up costing plenty more in long run.

 

i talk to a lot of racers in different parts of the country and a lot of guys use the import heads, but all buy them bare and have the set up done by someone competent or do it them selves. if someone bought a dart head with bad guides or badly machined valve seats, and it does happen you would send them back. well if you get a bad casting, send them back.
I've heard stuff like this about every single performance part there is and it borders on childish. if you know what the hell your looking at you will be fine , if you don't it is your peril. spending more doesn't guarantee you anything.

 

I completely agree.... So many people here have Chinese parts on their cars and choose to live in denial on who made them and where because they paid for a name brand and mark up on them...The reality is depending on who you purchase them from and how they were setup you won't have the issues... for example skip White goes through and tests the ones he sells and you can buy ones that he has cnc'ed and such for much less than others.... for a mild build they perform fine as most budget heads do. They need more work to flow in extreme HP builds as they should.
Its funny because the dart heads I have actually have a high failure rate on the guides duty you don't see that mentioned here mine failed and had to be replaced prior to me purchasing them used.... Just the same old pay more for better quality line.... If that statement were soo true we would all be driving Ferraris here and not the cheaper, cheaply made and quality control issue prone Chevy C3 right?

 

Im sure we all have import parts weither or not that we know it. Buy the time you buy the import heads, set them up right, get them ported unless your a head porter you've pretty much invested what a set of quality heads cost. I know that afr are american casted as edelbrock claims also, I wouldnt see dart being import castings either although until now I hadnt heard about darts guide failure, its about budget, goals and combo.

 

I think the Chinese are as capable of producing quality products as anyone else may be given a motive to do so. So long as they can sell a product which may not fail right away, people keep buying, there's no motive to improve.

Seems the Japanese were in this phase from the 50's to early 80's..

 

The AFR heads flow better period. They also may be overkill for the guy just wanting. To wake up his 350 a bit... my point is a 383 or 400 has more cubic Inches and therefore can flow better, producing more power than a 350 or 327. But not everyone feels they need a 383 or 400 whether its cost or whatnot that often decide a 350 is enough. Just like the heads about can easily wake a stock engine up with a mild can and mame 350-375hp without issues.... if you feel you need to squeeze every last bit of power and have changed the rest of the engine and drive train to support it then to me yeah better flowing out of the box heads may certainly be the better choice. The Op wanted feed back on these heads, he didn't ask how they stacked up to the best. And the bigger picture is how didn't stare how he planned to use them? A mild stock looking engine with a stock or performer intake and exhaust with cats? Or with a big can and high rise intake and headers? If you Google dart head valve guide failure/ issues you'll see a lot of examples.

 

FYI edelbrock is making more intakes and accessories in china now... it you read the summit or begs catolog closely you'll see some are advertised as made in america and some aren't.
Like I've said many times of their knock off carter carbs they make in china from ancient weber molds.
Just because its from china doesn't make it jink and people need to stop referring to every head that comes from there as being the same... its a big country with many manufactuers. You got real Iphones being made there as well as knockoffs.

 

I'll stick with parts made in N.A. and I'll say it again I wouldn't put any head made in China near any engine I would build. They are junk, period.

Any of you comrades willing to build an engine with 100% Chinese parts ?

 

I really don't think that much needs to be changed to support 400 horse unless the vette in question is in such bad shape that an engine up grade should be put off. I'm not doubting you on the dart guide failures and don't need to google it as I'm not buying any dart heads, but if I was I'd research the product until I was certain that what I was buying was indeed what I wanted. If I were going to build a 350" I'd go with the 180cc eliminators and even with a flat tappet camshaft You can make over 400 horse with excellent street manners using a camshaft along the lines of the xe 262 or the xe268. This doesn't mean that spending money on decent parts is for everyone and the same goes with buying a cheap head and porting them and making them work as well if not better than the more expensive head as not having a flow bench and or a dyno leaves all the work in my case as only a best guess and with out the experience of porting heads it would be my luck that I'd make them flow worse. There are plenty of quality heads out there that flow well enough to make serious power on a budget, patriot performance made a 383 that was 500 horse using there 195's which don't flow all that great, not bad, just not great and their camshaft was 246 @ .50'' on the intake alone making streetability a little tougher to tame, You use the fast burns and you like them, and from your last thread it would seem that they make good power on a 350'' and they don't cost what some other heads do. I think that you'd agree that they would be a lot better route to go over the ebay cheapo's unless you've got porting skills and a machine shop. Al tthough not every vette owner starts out wanting a ton of horse power in my case I started out just wanting more power than the pathetic 180 horse that my 76 c3 came with and for me once I got it, it was great but 2 years later I wanted more and I don't think that it will ever end. Just my opinion.

In the case of edelbrock, the airgap that I got came with made in the usa labeling and as we all know proven by walmart that don't meen crap, but at least it didn't come with a made in china sticker.

 

There are intakes, heads etc which are proven knockoffs of Edelbrock and Dart coming out of China. Could they secretly be having them made there as a "competitor" brand to get 2 schools of buyers who knows..doubt it though.

Thought there was a line of the ProFiler heads that are the China heads that Chad makes some changes to

Look down inside the intake runner on those types of heads youll see something similar in all of them (the cheap import heads). Not for me.

There was a member not too long ago who bought a set of the PC/Promaxx etc heads had his machinist go through them etc only to go put his rockers on and found the studs were in the wrong locations, spark plug holes too.Seats falling out yikes

Youll hear a few guys that post they love theirs "no problems". Report back in 15-20k miles, havent seen it yet.

Are there some good sets running around out there sure there are.
Couldnt give me a set too much $ to risk.

 

There are no pro-filer heads made in china! They are cast and machined
in New Carlisle, Ohio.Chad does rework a procomp import casting for the bugdet crowd.For the record Dart heads are cast in Ross,Ohio then machined outside detroit.There are several others as stated earlier that are also domestically produced.Pro-filer is division of Htc castings whose primary business is investment castings for the aerospace industry.They also do castings for ford pro stock,mopar pro stock and many others.
