Okay... it's the LS/VTEC All of you who have been paying attention know the drill ;-)

pistons have a 5.7 dome.
b18a block, b16a head.

Head has been milled .040
Head Gasket is .067 thick (cometic)

Someone clue me in on how I can calculate my comp. ratio from that.

What I'm guessing was 12:1 is actually more like 11.5:1 but it's hard to figure out how much the milling of the head did to my comp.

Anybody got a clue how to factor in milling of the head?

P.S. would a good-old compression PSI check help me out any?
