rlracer Posted July 1, 2010 Report Share Posted July 1, 2010 Maybe S3 ? or have a stock head machined into a high compression head. Quote Link to comment Share on other sites More sharing options...
kramit Posted July 2, 2010 Report Share Posted July 2, 2010 Try about an .008 to .010 thinner base gsk. But just to be safe, ck the comp. ratio before running. Quote Link to comment Share on other sites More sharing options...
copemech Posted July 2, 2010 Report Share Posted July 2, 2010 Try about an .008 to .010 thinner base gsk. But just to be safe, ck the comp. ratio before running. Unfortunately , that will not work here as the base gasket is nil and the head is o-ringed. I would guess that anything past .001-2 taken off the head surface on a platter or mill would also require the re-cutting of the o-ring grooves deeper to compensate. The squish band here is already narrow. Not much to play with. Ring up Paxau! He knows something! Quote Link to comment Share on other sites More sharing options...
