Alum heads

[Jim]

What's the chamber size (CC's) on stock alum heads?

Which head Jim?

I found this at Scoggin-Dickey :
The Vortec - High Performance Assembled Heads have a chamber size of 64cc, while the "Fast Burn" Aluminum Heads have a chamber size of 62cc, and the Splayed Valve Cylinder Head have a chamber size of 45cc.

So you see that you should be a little more specific with your question.

Stock L98 alum heads.

I believe it is 64cc Jim.

I thought the stock aluminum L98 heads are actually only 58cc. The factory head gasket is extra thick. That drops the compression less than what you would expect for such a small chamber.
