What are the compression numbers suppose to be for a car that has 9.0:1 pistons again?
 
I'm guessing at least 180-190. It depends a lot on if your head / block have been resurfaced, how thick your headgasket is, and what cams you're running. How much do you have?

Both head and block resurfaced when built with stock cams. Block is a 2.4L G4CS. I don't know what you mean by "how much I have?" What do you mean by that. My compression numbers came back 205 across the board.
 
To my knowledge, this is perfect reading for a 2.4L with stock cams. If I'm wrong, someone please correct me.
