Well my rings on my B16a went bad and I found a pretty good deal on a B18C1 Block with ITR rods and Pistons. Now I know that when you put a B16 Head on a GSR block you lose compression, but what I am wondering is how much will be lost considering there are ITR pistons installed?

there you go. essentially, you have the exact same compression because you have a pr3 head on an ITR internal block. you got the right answer
