2 Head Gaskets???

The 7.5 cc number is the total dome displacement counting valve releifs and the piston flat area being 0.10 out of the hole. I poured the cylinder with the piston .500 down the bore. Got the volume of the bore and stroke times .500 then subtracted the volume from what I had measured. That was my dome volume.
The head gasket is 3.490.
I guess I'll have to run the thick gasket. 14+ comp ratio will be way to much for the cams I'm running but I can play with overlap due to 2 cams.
