thanks for checking. I was just going with what SRP.com says.

OK, I see where that came from. Here you go:
B16 engine with B16 head: 9.8
B17 engine/head: 10.0
B18A1/B1: 11.0
GSR engine/head: 11.0
ITR engine/head: 11.0
Those are the compressions they list on stock engine/head combos (seems kind of odd that the GSR and ITR engines list the same compression since they have everything the same except for the head; the GSR should be slightly higher). If an engine comes with a B16/ITR head but you'll be using a GSR head, add approximately .2-.3 compression. If it originally was fitted with a GSR head but you have a B16/ITR head, it will be about .2-.3 less compression.
