while everything was apart so I did a cylinder leak down test, all valves held tight but could only get about 40% on some cylinders and the best was 60% had air leaking out 3 spark plugs holes so I pulled head and yes they did use steel shim head gaskets in 1973. but compression was good.It seems every time I go to fix something the engine allways comes apart!so more parts to the machine shop on monday!
