: Compression readings on 10:1?

I finally got around to doing a compression check on wolfcri's blue egg, since we finished the JDM swap earlier last week.

Cylinder 1: 205
Cylinder 2: 205
Cylinder 3: 203
Cylinder 4: 200

I don't know if .5 difference in compression ratios can do that much as far as the readings were concerned, since stock readings on a 9.5:1 motor are supposed to be 178psi, so we've concluded that this is a 10:1 motor.

Any thoughts?
