I did a search but the search function is pulling up posts from 2003. I am seriously considering buying a set of AFR 205 heads for my 99 Corvette coupe however after talking to the vendor where I am getting my cam it seems he HIGHLY recommends ETP and/or Trickflow heads rather than AFR. He says the valve angle allows more ptvc which will allow me to use a larger cam without flycutting the pistons thereby providing more power.

Any opinions, facts, etc is highly appreciated. I want a cam in the 232/236 .60/.605 112 LSA range.

trickflow's are pretty sweet heads. HPE was getting really good results using them

i think trickflow is making the sickest power right now!! but definitely dont count out the afr's!! i dunno much bout the other brand of heads though. but u cant go wrong with afr's or trickflows for sure!

Sounds like you need to call the crew at LG Motorsports. I would suggest the AFR 205's. Proven performance from the AFR's no matter if you are using a small 224/228 Mamo cam or a larger G5X3 sized cam. The AFR's maintain a nice area under the curve and good off idle/mid range torque. I would suggest having them milled to 59cc for better compression and running cometic gaskets. Call LG, they have plenty of experience with proven AFR combos. Hope this helps. Good luck.

I seem to remember the ETP's required some modifications to the alternator/bracket to install on a Vette. They also require very long pushrods and some guys were having valve train stability issues. I would consider 3/8's pushrods with the ETP's. The Trickflows seem to be nice heads, but they do require a different rocker so make sure you figure that into your cost trade-off. AFR 205's have provided consistent performance and seem to give good mid-range power. Not sure where the cam you have will make its power, but the heads can help keep the lower RPM range from getting too soft.

Thanks guys all good stuff and helpful. So far I am planning on staying with the AFR 205s that I am getting. Any other input?

Whatever you choose, look for heads with excellent flow in the .300-500" range if running a plastic intake. Flow in the .600"+ range is irrelevant. Also, get as much compression as you can get while still maintaining proper piston to valve clearance. For me, the AFR 205s fit the bill.

I like the AFR's the most. geometry is dead on and theres no effort .bolt them on and there money. both ETP and TF we have had to shim and stuff to get the rocker arm travel right. also TF had some issue where you can't use the stock style rockers. I love the Harlen sharme stock replacments they work perfect on my AFR's

what sponser sells trickflow, I always thought of trickflow as those cheap heads that jegs sells.

AFR heads have a much greater valve drop than stock. If you were to run the cam you listed above, there is no reason why you would need to notch pistons to clear it. Even after milling for the best DCR, you'll still be in good shape. Since someone already mentioned LG cams, Louis was the one who has pointed out previously that AFR 205 heads milled to 59cc have greater valve drop than stock castings.

Get them milled to 59cc, run a .040 thick gasket. That should get you 11.83 SCR and 8.79 DCR, according to PianoProdigy's DCR Calc in my sig. You should have excellent drivability and no worrys of detonation at all with the tight quench.

Good Luck!

TEA sells them and I believe does all the machining on them as well.

I love my AFR 205s. I only have a mild cam, but it still makes the number, and without a 90mm FAST intake/TB setup. I wouldnt hesitate to go with them again. The only other head I would consider, would be the TFS 215s.
