superbmobile Posted April 20, 2008 Report Share Posted April 20, 2008 My 4k blew the head gasket so Its a good time to get the head shaved to give it a bit more power how much would you recommend taking off I'm thinking around 20 thou but tell me what you think. :dance: Quote Link to comment Share on other sites More sharing options...
Redwarf Posted April 20, 2008 Report Share Posted April 20, 2008 Ten to twenty is what they'd take off in a normal sort of skim. I once had a head that was shaved .125". The screwdriver holes for lifting the head off weren't there anymore. Twenty would be fine. As would probably anything up to .060" Quote Link to comment Share on other sites More sharing options...
harun Posted April 20, 2008 Report Share Posted April 20, 2008 (edited) 40thou sounds sweet. Snap bang in the centre of 20 and 60 thou. Make sure to clean the deck of the block aswell, so that your new gasket can sit in flush. Edited April 20, 2008 by harun Quote Link to comment Share on other sites More sharing options...

Redwarf Posted April 21, 2008 Report Share Posted April 21, 2008 Well, it was back in the days of AvGas, thus we were looking for 11:1 plus. Can't remember what we ended up with, but it went well for a while. Quote Link to comment Share on other sites More sharing options...

Redwarf Posted April 21, 2008 Report Share Posted April 21, 2008 Meh, it really just wore out. Nothing went bang as such, it just got tired after about two seasons. Quote Link to comment Share on other sites More sharing options...
