ive been using this site to see possible compression differences, but i was wondering if its accurate

for example my motor is stock 81mm bore LS bottom end with type R/B16 head. pr3 pistons and stock head gasket

it said that the cr was 11.3 correct?

 

i know it is inaccurate to the point of B16 blocks, it says the B16A/B are the same, which is totally not true.

correct
i think its preatty much accurate

 

it is off on PCT pistons by about .2

 

i was just messing around and i calculated a b18b block/head and oem head-gasket with ctr pistons and it put out 11.4. Is this possible? would it be even benificial for me? this would be greatly appreciated.

+/- .2 on the PCT pistons?
