Compression and Cam selection

Bakerlite said
Well I have it at 10.2 with the numbers you have posted and 10.3 if those pistons have 6cc valve pockets as listed.
Having said that, you won't be using a .039 gasket with those pistons

The 6cc is wrong from what I understand from KB. They said to use 7.3.

I'm going to have my machinist measure actual compression,.so I can be sure and go from there.
