didn't realize trw had dish pistons 20 yr ago. only -7cc 4 valve relief slugs. Arent #13's 72 cc.....at zero deck that would be more like 10.5 comp? My TRW's were .020 in the hole with 74 cc heads = 10.1 compression.
I'm sure you know more what you got than I do, but those numbers just seemed off.
ANYWAY...more compression will be better, zero deck is even better...now at 10.5:1 compression I would expect even better bottom end numbers as that is a fast action cam so you will not be bleeding off cylinder pressure as much as the 041 does. = even more torque
