Aluminum heads
#2
AFR doesn't make Oldsmobile heads that I know of. Procomp are similar and a good deal from Benard Mondello. The heads with a 350 need the chambers milled to 70cc to take full advantage.

The current Edelbrock heads have a new chamber that may or may not be better. Procomp is a copy of the original Edelbrock but the components are pretty cheap and they can use some final machining/clean up. Don't trust the valve guides. Hence get it from a trusted Olds vendor like Bernard Mondello (*not* "Mondello" in california).
