I need help to specify an AFR 190 head for a 350 TPI for an 87
Iroc. There is some extra machine work needed on the heads for a TPI unit , if you had ordered before please help.

I may used this heads on a stock 350 L98 block or a 383 strocker 1971 block, 4 bolt main.

Thanks for your help,

 

I just ordered a set of AFR 190s. For TPI you need the L98 angle plug version regarding headers you might be using. I imagine you want to keep them emission legal so indicate that also when ordering. Basically they have to be drilled for a TPI base (intake manifold)bolts.
I also had mine milled to 64cc for more compression. The tottal was $1450 shipped. $1300 w/out the extra milling.
The whole thing about AFR is that they litterally make the heads from scratch from the time you order them so it'll takes between 2-6 weeks before you get them. I'm still waiting for mine and it's been 2 1/2 weeks. I got them from Dave at www.tenperf.com. He seems to have the best price as far as my research and comes recomended by a moderator from these boards.
Hope that helps

 

I ordered AFR 190's. Just call aFR and talk to the sales rep. Tell them what year car and they will hook you up.

I did mine in like 95'. I think I had the heads milled to 58cc. a heat riser for emissions an coolent temp sensor are drilled out. It cost 1400 bucks. Also, I ordered ARP head bolts and Fel-Pro gaskets.
