I put on a set of heads and performed a compression check to make sure everything was sealed good. I read over 220psi in all cylinders and as high as 250psi. Is this normal or did my gauge take a crap? What psi numbers does everyone usually get?

-Thanks,

Have you ran the engine yet? Do you have another gauge to compair it to? 250 would be getting into the diesel engine realm <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" /> <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" /> <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" /> <img border="0" alt="[bomb]" title="" src="graemlins/gr_bomb.gif" /> <img border="0" alt="[cry]" title="" src="graemlins/gr_cry.gif" />

 

What is normal for a engine w/ 30,000 miles? I've got a LS1 w/ GTP heads/Pig cam and my compression test is reading around 135-140 per cylinder. I think we have a problem! The valvetrain seems to be noisier than it should be. I did reuse my stock rocker arms. Any help would be appreciated. Thanks
