Default Question about Big Block Heads?

What is the chamber size on the original L36 heads.
These are the small chamber oval port heads.
My heads have been given the larger valves 2.19/1.88 but, I would think that the chamber size is still close to stock. :confused:

I have cc'd heads like this and got around 106 to 107 cc's. I don't know what they advertise them at.

Thanks norval,
I was told that due to the small chamber they were able to keep compression high. :cool:

GM says they are 96cc, but most people like Norval who have actually checked them say they are around 100cc or a little larger.
