Around 7.8:1 or something in that area. I couldn't tell exact seing as how I don't have an exact measurement of the pistons?

AVATAR: around 8.3:1 I believe.

You'll both lose compression because the differences in the head sizes and the pistons are made for that compression with the specific head designated.

Gee, how many people here use multiple accounts? Would you two know?

So am I, heh. More importantly than numbers I want to dip into 11s (sounds far fecthed but something to shoot for). I'm going LS/VTEC.
Tzsir- if I'm looking for 9:1 or 9.5:1 CR I should buy 9.5:1 or 10:1 pistons with the B16 head?
