Default Heads opinion

Hello all I'm working over my l98 and was wondering what your thoughts were on these heads.
http://cgi.ebay.com/ebaymotors/sbc-c...item2566fd5c95

I would order the 190 with the angle plug with the 64 chambers. I've not yet picked out a cam yet and I'm still debating on whether I can swing AFR's from Jim. I called and talked to the guys at firstfuelinjection and will be getting their intake setup.

If these heads are ok they represent enough savings over the AFR's that I could spend more on the tune or maybe go with some obx headers. I'm not looking to start an AFR vs the world debate again I read enough of those with the search function.

So these heads, try for the AFR's or go for a brodix or edelbrock? With my limited knowledge should i just be looking at top end packages which have the head and cam together?
Thoughts? Thank you.-just a street car, no racing.

Search ProComp see what others have said. Brodix/Dart are much more cost but some say worth it.

Hey Jeramy, if you go with AFR's, you would want the AFR 195 heads #1040 unless you are using a Vortech style intake. The AFR 190 is a Vortech specific cylinder head.

I can take a set of 2000.00 castings and make them junk in 5 minutes or less.


Dont skimp when it comes to heads, if youre going to use the FIRST def. get the AFRs


Maybe those are Ok but those ads for the cheapie heads all look the same, their buddy works at a track they even got stickers on their car, their dog watches Nascar with them, etc. Not one flow # on there either.
not really confidence inspiring

If you change to 64cc chambers you will lose compression are you changing pistons? or deck height or head gasket thickness

Thanks for steering me back straight Jim. I'm planning on running the stock pistons so I'm thinking a thinner head gasket to maybe bring some of the cr back. I will avoid these types of heads in the future then.
Opinions on the edelbrock top end packages? If I have to spend 1k on heads then I'll just order the afr's from Jim. I was just thinking that maybe an $800-$900 set plus headers would do me as well as a $1300 set of afr's. I will also check out the procomps and brodix as suggested.

Do I read the ad correctly, $750. for one head or is that for a pair? If that is for a pair I do not see how he can do it. Springs and valves alone would run almost half that.

You can get them milled to correct chamber size.

Badduck would you use a thinner head gasket and mill the heads-or just mill the heads and use a regular head gasket?

Depends on your goals and overall setup. Milling can cost $'s. You might get a quote. BTW, if you don't go with AFR's you will get shouted down on this forum.

You cant use the stock manifolds with the AFRs,in fact even with other performance heads you should run headers, youll only be choking the motor. You will get what you pay for with heads. Save a few hundred make noticeably less power, nothing will make up for it. made that mistake yrs ago and totally regretted it. "The almost the good as head for $200 less" I picked up sucked, didnt feel much different than stock.

You can flat mill the AFR's to 60cc's. Beyond that will require an angle mill. A flat mill and a thinner gasket would bring your compression right back to where it is now.

When you say I cannot use the factory headers with the afr's is that because they won't fit or just because it would be a silly thing to do. I ask because I purchased some hedman longtubes for the l98 heads which I never installed. If I got the afr's I was going to use them instead of buying the nicer obx's

They wont cover the exhaust port and they are extremely restrictive.

Ok I broke down and gave TPI_421 a call. I like dealing with him because he's a good guy who knows his @#!. Ordered AFR 195's that I'm having AFR flat mill down to 60cc's for me. AFR's doing the milling and will make sure they don't cause me any alignment issues with their work.

It was a bit of money for me to cough up at once but in the end I think it will be worth it. I didn't want to have to worry about bad springs or things that were prematurely wearing because they used @#! components. Jim got me the heads flat milled and shipped to my door for right around what just the heads would have normally retailed for.
