Compression ratio?

[heavychevy98]

Im sure there is info about this already but i cant find it, but what compression ratio will i be running on stock vortec engine, standard deck, heads cut .015 and a .038 felpro headgasket? What cc will this bring my heads to? and what cc displacement and compression height are factory pistons so i can figure quench/static compression on my own.

Not sure what heads would end up being if you cut them down .015, but stock they are 64cc.
bore: 4.0
stroke: 3.5
cylinder head volume = ??
standard deck: .025
piston dome volume: 12cc
deck clearance: .025
gasket thickness (compressed?): .038


With the numbers above here are a few compression rations you'd end up with with different head volumes:
64cc = 9.1:1
60cc = 9.49:1
55cc = 10.01:1
50cc = 10.62:1
