408 build and results.

I don't have the block here to measure exactly, but at zero deck height the summit calc puts me at 14:1 with .045 compressed thickness and 11.45:1 with .120 compressed thickness. Which makes complete sense because with OPs +20cc dish the calc puts him at 10.36 with .045 gasket.

i doubt your anywhere remotely close to 14 to 1 with flattops.
I have the Icon flattops. They are roughly 11.5 compression with a 70 cc head. 12.5 with a 60 cc head.
