having just picked up my new head I wanted to do some calculations for the compression ratio. its a 2ltr pinto
I tried doing it long had on a bit of paper but went massively wrong, would one of the resident experts on this confirm if this online calculator is correct.

these are my numbers and my answer
bore 90.07mm or 3.570866'
stroke 76.2mm or 3.0'
felpro gasket 1.0mm or 0.0394
distance from top of piston at tdc to deck is, 0.381mm or 0.015'
my head cc'd at 44cc
all that said I got a ratio of = 10.4 does this sound right???
