Default Re: sealing copper head gasket

I had copper gaskets on my biblock from 1999 to 2007 when the engine finally blew up,and had no failure,so maybe my setup worked.I had an O ringed block and non grooved heads with .060" thiick gaskets.I used blue hylomar gasket spray.I put a heavy coat on the block and heads,and a few coats on both siides of the gaskets.I let it set up for about 10 minutes,then layed it all together and torqued the heads down right away.I did add a little tube of cheap stop leak as insurance,but I never had water in the oil no matter how much I accedently overheated it or shot tons of nitrous thru it.Good luck.

Thanks Rich. I had a .078 gasket, and am going to a .062 assuming I don't have valve clearance issues. Will find out tonight. Block is "O" ringed and head has receiver grooves.
