I have used the 262/305 head gasket many times with my combination. It was old G.M. part # 14085906 & older part # 362690 and was also made by McCord. They were .016 thick & cross to currently still available # 10105115. The first two are steel shim while the third one has a coating on it & measures .025 thick so not a straight cross. As far as size I believe they are 3.910 compressed diameter but I will measure an old one and post that number later.
