i did think about getting the head skimmed but was a bit worried about the cr cos i think im pushing my luck as it is. perhaps il have buy a cometic gasket (1.6mm) and have the head skimmed, hopefuly that should last a while. im not sure what caused the gasket to go but it only lasted about 2 seconds and cut a 5mm slice out of the head, pos to much nitrous presure
