Looking for stock L98 cylinder heads
Hey guys. I'm looking for a set of stock #083 casting L98 cylinder heads for my car.
My cylinder heads cracked when the motor overheated and I need to swap them out.

I have a set of stock L98 tuned port heads. Iron heads. $300 plus shipping. Work great no problems.
Corvette heads have a different combustion chamber volume FYI. It will raise your compression ratio.
