There is alot of forum members using AFR heads. They are great performers out of the box. In fact I am currently finishing a 383 buildup that includes AFR 195's.

I would not add the heads unless you do more for the engine. They are expensive and without a corresponding intake flow and cam they will not perform to maximum. If you are willing to change heads - go a little further and change cam and intake and make a performance difference.

You dont really need them until you start significant mods. For a stock or near stock replacement on the 85, id use 88-91 vette heads.

i thought the center int bolt holes were different on the 88-91? ARE THESE THE ALUM HEADS?
What would i need to do to put these on the 85? And where do you recommend buying them? I know autozone sells them

These are Aluminum heads that came from the factory on 88-91 Corvettes. You can find them in a junkyard, or buy them off ebay. All you would probably need is new valvecovers for the centerbolt heads.

Yeah, I would go with a factory head, if you dish out the cash for AFR heads, make sure you get a good head. 190 or 195's
