That is a good idea, thank you. I hate these stamped steel gaskets for that reason- the tiniest warp or imperfection and they won't seal. That is why I am considering making my own gasket out if a sheet of high temp silicone. Only thing stopping me is I'm not sure how compatible silicone is with gasoline and I can't seem to find an answer since it appears that compatibility varies based on the specific silicone used.If it were mine I would get a good steel straight edge and some good feeler gauges and check the head. TRUST ME, it doesn't take much for an aluminum head to warp.
