Stock 5.7 Heads vs L98 Stock Corvette Heads
I was curious about the differences between the two heads. I am working up a set of L98 heads. I do not know what the CC of these heads are. I figure the weight alone is worth something. Thanks, BranT

To my knowledge, the only difference between the two heads is the material they were made out of. They both come from the same casting I believe.

The aluminum vette heads have 58cc combustion chambers (as opposed to 64) and a different D-port exhaust. The intakes are pretty much the same. The vette head does not have the heat riser/EGR passage in the head, on a corvette it gets exhaust gas for the EGR from the RH exhaust manifold. Something to consider if emissions are a concern.
