Needing advice on 360

before you remove the other head put compressed air in each cylinder and check for leakage with rockers removed or valves closed. also look at the top of the pistons and plugs. The cylinder that blew will probably be steamed cleaned and shiny. Mr gasket thin head gaskets are not .028 compressed. I measured the gaskets that were removed from my brothers engine and they mic out to .034 compressed. I also measured new ones and they were .039
