compression ratio question

[DSMer541]

im wondering if anyone can help me figure out the final compression ratio of my setup, i don tknow the mathmatical calculations to do it......i got 8:1 pistons ,85.5mm bore , stock stoke (88mm?), a 4layer mls head gasket, and the head was milled if that makes a difference. it would probably be right around stock ratio for a 6 bolt right? thanx for any help

You have 8:1 pistons so unless you shaved a crazy amount off the head, switched to a 4g37 head or used a really thick headgasket you're going to maintain that compression ratio plus or minus .1.
