High, but uneven compression
I just replaced the head in one of my project 22re trucks. I got the following for compression:
#1 160 psi
#2 185 psi
#3 190 psi
#4 195 psi
Does that sound right? I'm sure that the replacement head wasn't shaved, but I could be wrong. I'm wondering if my compression gauge is all wacky, and I'm worried about the apparently uneven readings.
Any comments?

Even if it was shaved that wouldnt account for the uneveness, unless it was shaved on a slope from front to back
I'd run it for awhile then redo the test.

Run the test several times...get another another tester....ie, rent one, borrow one....and see what differences you get. Otherwise, maybe the valve tolerances are off. Check'em when in doubt....if in doubt.

I'd pull all the plugs first so its easier to for the starter to turn the motor over.
Ive herd that usuing a charger suposidly(sp) keep the rpm's from one cylinder to the next more consistant but I've never used one or had any problems otherwise.
