hi there guys,
i was just wandering what you reackon are the best value heads dollar wise out there on the market please?

i really like the air flow research heads 195 cc range but they are alot of money bye the time i have converted from u.s dollar to aussie dollars!
afr heads are from $1,440 u.s up too $2,017 u.s complete plus shipping!

im after around the 195 cc size but must also have lift capability of up to 600" lift in the valve springs!

if you have brand name,specs,links to some good quality cheaper aftermarket heads can you please let me know!
thanks guys
cheers

I used Trick-Flow 195cc 23 deg heads...
very good heads and around 1300-1350 you can have the CNC combustion chamber verson.

I believe they are Canfield heads marketed by Jeg's ; Flow Chart is listed also.

The best dollar valved heads on the market right now are the new AFR's Eliminator's. If you hunt around they can be found for under $1350 USD. They will outflow any 195 head on the planet right now out of the box! If you are building a 350. The 180cc AFR head would be perfect!

 

Do a search on AFR heads before you buy. Here is a couple of links there are many others.

After speaking to AFR. They have told me that those problems wont happen again. The heads are triple checked before leaving the company. I think they care about there image. You can have problems with an part you order. A friend of mine just got his. They are top notch!

 

i disagree with this statement. it's going to take a couple of years before these guys can assure the public that their oil return issues and brittle valve tips issues wont happen again. i would use extreme caution when buying afr heads and living down under. if something were to go wrong with your heads you would have to ship them back to them from australia. if you get the afr heads, i would wait
a little and read all the forums where these heads are being used and see what actual users ahve to say about these heads.

All the magazines and afr employees are going to swear up and down that these heads will not have any problems.

if you cant wait go for the trickflows.

and most definately read the threads searched by kool88vette

 

I sold my TFS heads for the AFR heads. You prob think I took a gamble. I was willing to do that. You are right, We have not seen any data on these heads on motor like our, but we will soon.

 

try an outfit named white performance 1 they are in TN some where they got some great prices on heads with very good flow numbers, also RR and other parts:

 

I agree wholeheartedly. Due to your location, you'd be in a bad situation if you have any problems.

To touch base on that last bit of advice...
Has anyone seen, read, or heard of anyone actually using these heads right now?
We've all seen the flow numbers everywhere, we've all heard the hype, we've all read the numerous magazine articles...but does anyone other than a magazine (or AFR) have any real world opinions and/or experience with them?

I actually ordered the 180's for my car, but after thinking it over, I knew I'd never actually "need" them for my setup (assuming all the hype is accurate), so I cancelled the order and went a different route.

Just curious if anyone actually runs these heads presently...

 

hi there guys,
thanks for all your comments/help!

those (canfield) heads marketed by jegs look alright for the money and specs dont they?

reading the specs they have would they be good enough for plenty of performance?

thanks guys
cheers

The Brodix race rights are another one to consider. I was very, very impressed with the quality. I installed them on Beppe's (conv90) 396. Price was fair. Approx $1350 shipped to my builder.

 

Bob, I have seen no "real world" data as of it. But if you look what you get for the $$$. I am of the opinion it's a no brainer, and so are alot of other guys.

 

Glen. Have you looked at the AFR 180's? Since you are over sea's. You could have a problem with any head or any car part sent over to you.

All the heads mentioned are quality heads. I know from experience the Trickflow's I had were of good quality.

 

Dart heads are also very good and fairly priced, I have a set of 180 Iron Eagles on my 350, and I'm very satisfied with them.

How about the old New Zealand made Pro-Toplines?

I think they're now owned by Comp/RHS. Perhaps these would be cost effective if they're available in Australia.

Just stumbled across this article on $1000 heads:

After reviewing the flow chart, the intake side is VERY similar to AFR 180cc eliminator heads, however what bothers me is on the exhaust side the 180cc Eliminators have this head beat by almost 20cfm at .500 lift.

compared to the 195cc eliminators (almost even intake port volume): through low-lift numbers the AFR head is slightly behind on the Intake side but the exhaust side is continually above that of the JEGS head - around .400 lift and up the AFR head shows serious muscle and is flowing 286/215 at .600 lift while the JEGS head flows 259/200 - depending on the cam you get this could mean a big performance difference. - if you have the cash i'd get the eliminators.

Compared to Trickflow Twisted Wedge 23deg head: JEGS eats it up low-lift and leads till about .400 lift. Trickflow pulls close on the intake side at this point but continually lags behind in exhaust flow. I'd say Advantage JEGS here...

what really needs to happen is a good sit-down with you and the car and decide exactly what power level you want. From there you can then select a bottom end and a good heads/cam package to match. It really doesnt matter what the heads flow at .700 lift because you will never have that in a "street" car...good flow under that lift however is extremely important. usually most people stick to around a max of about ~.600 lift. that is more than enough cam (with the right duration) to make you seriously ludacris amounts of power with the right setup as long as its matched...

But back to the heads...i would consider the JEGS heads an economical bridge between the twisted wedge heads and the AFR Eliminator series. With a properly selected package of displacement, cam, compression and those heads you should be able to make more than enough power for everyday street use and still hold your own at the track.

In fact, now that i think about it...they look good enough to try a desktop dyno sim on my fantasy 414-435 build

EDIT - over brodix IK180cc heads used on my 414-435 simulations in Desktop Dyno the JEGS head delivers ~7-15hp and about the same for torque. they will cost you about 100 bucks more than a set of IK180cc heads and only give you an avg of about 10 more hp according to what i see. wether or not that is worth it is up to you and depends on your engine build.

One thing i will say is they must use some beefy springs on the JEGS heads since they show a max of .680 lift? the IK180cc heads are available with CC987 springs which only allow for .575 lift according to the brodix site...

 

Why would you install a 180cc runner head on a 414-435 cube motor?

 

With the 434 builds, it is very hard to put enough cylinder head on them to use them to their full potential. I am very conservative and often use head and cam combo's that are considered way too small by others. In my opinion, a tiny head for a 434 is 210cc's
