Hi All, I am rebuilding a 600cc engine and the oil tube seals that came with the gasket set are the thick ones, when tightening down the head they seem very tight to the point I am worried about cracking the head above them. I have torqued the head down but am not sure if he new ones will prevent the head sealing . If I can get new silicone O rings at the local hardware store would that be ok?
