FranciscoR92 Posted September 11, 2015 Report Share Posted September 11, 2015 Hey guys i just bought a pair of 799 heads from KHP yesterday. He recommended i mill them .040 to bump my compression even further than just a simple head swap from the 317s and use a stock GM gasket on my LQ4, like a dumb ass i forgot to ask if it would affect my PTV clearance with the cam im about to put in. Its a custom grind 231/239 .617.623 114 lsa anyone run a similar cam and or setup? figured i'd ask you knowledgeable fellows Quote Link to comment Share on other sites More sharing options...
zippy Posted September 13, 2015 Report Share Posted September 13, 2015 With yours being an LQ4 you should be plenty fine with the stock gakets. The LQ4 has plenty of valve relief so you should be plenty fine. Just call the dealer with your vin and order the stock gaskets. Quote Link to comment Share on other sites More sharing options...
