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,

 

Havne't ordered one but you'll want EGR passages if you're staying legal, you'll need temp sensors on each side, and the 3 bolt holes on the front (and back) for accessories, the rest is up to you.
