So you have a 2.065 compression height piston with a 14 cc dome and stealth heads in a + .030 440 with a .040 gasket.
You compression will be about 12.5 to 1

Stroke 3.75
deck 0 deck
Dome - 14 cc
Head 83 cc average
gasket .040 average about 10 CC
Displaces 913 cc per cylinder
effective volume 83 + 10 - 14 = 79
913 + 79/79 = 12.55 to 1
