Default compression results

let me know what you think, listed in numerical order(1-2-3-4):160-155-145-160. are these normal? Just rebuilt the motor about 4000 miles ago, put je pistons in cr=9.5 with gs-r crank and eagle h-beam rods. cylinders bored over 20 thousands. It is a b18b motor, it just doesnt seem right to me, maybe kinda low. let me know what you think.

I would think a motor like that would be closer to 180 psi.

yeah, i think i am losing oil in #3. i havent done the oil in cylinder test for the valves yet though. lol once apon a time i did a valve adjustment and may have slightly bent a valve just from tap. nothing serious enough to break anything. but i am gonna do that very soon. I have a few extra valves laying around that i am sure i can use. Are the GS-R valves the same size as LS??
