Wildcardracing Posted July 7, 2009 Report Posted July 7, 2009 I wouldn't hightly recommend having the stock head milled without addressing the chambers. If you go too far your squish will be too tight reguardless of compression numbers and will lead to detonation. I can get as small as 19cc chambers out of the oem head with a mill/rechamber job. How small you will want to go will all depend on your elevation. I saw your other post mentioning porting, that would be the ideal time to have the headwork done to match the new portwork. -Brandon Quote
