nickxc Posted August 13, 2004 Report Share Posted August 13, 2004 I put a straight edge on my head and I could see daylight under it so I am gunna get it shaved more to take the warp out of it. My question is I wanna safely run pump gas (keep in mind I live in the adirondack mountains and gas is lower quality here) I am currently running with 135lbs compression in each cyl. by shaveing my head more I will raise my compression more. How much compression can I run with pump gas SAFELY??? Quote Link to comment Share on other sites More sharing options...
nater006 Posted August 13, 2004 Report Share Posted August 13, 2004 How much did you already have it shaved down? Apparently if you go further than .030 you'll have to have the squish re-cut, which could end up costing more and not being as effective as investing in a Noss head or Cool Head.

boonman Posted August 13, 2004 Report Share Posted August 13, 2004 Buy a head off of Ebay, and use that one. Throw your current one in the dump...... Your squish will be frigged if you cut it past .030". How did it get warped? Quote Link to comment Share on other sites More sharing options...
nickxc Posted August 13, 2004 Author Report Share Posted August 13, 2004 idk how much it is shaved now It was done buy the engine builder that did all my other work and I never even asked. Idk how it got warped either. I just was going through head gaskets so I took it off and took it to a local stealer and they said with a straight edge on it you could see daylight in a couple places so it is no good...

ledofthezep Posted August 13, 2004 Report Share Posted August 13, 2004 I wouldn't run pump gas on anything over 160lbs compression. I run 93 oct. with Castor 927 @ 40:1 on 150lbs(about what you'll get by shaving your head .030). Quote Link to comment Share on other sites More sharing options...
