Engine builder installed Cometic head gaskets a couple years ago. After a few trips to the track, I brought the car to my regular mechanic for some non engine related work. He said my head gasket was leaking on pass. side and I should go back to engine builder. Since it is no longer under warranty, I would like to fix it cheap if possible. Could the head just be retorqued? He used ARP bolts, not studs. I had not retorqued it after the Cometics were installed. I asked the engine builder if they should have been retorqued at some point and he said no. So what are my options? Thanks!
