I will go with what Ruth said. I have also had bad luck with that gasket. Last gasket was the Best Gasket Graphtie #573 which is for B engines and high compression heads. I used the spray copper gasket sealer on both sides. The block and head have to be meticulously clean. I finished up with an acetone wipe. They also have to be flat with no low spots. I slightly dressed my head with some 220 wet and dry paper wrapped around a flat file. The head can be checked with bluing and a sheet of flat glass. Best to have it surfaced at a machine shop if in doubt. Ditto the block but that is more involved.

Torque following the recommended sequence in 5 foot-pound increments from 25 ft-lb to 55 ft-lb. Warm up the engine then let it sit overnight and re-torque. Drive it for about 50 miles, let it cool, and re torque. I am planning on re torquing my head at least 3 more times and then once a year.
