WELL... It's time once again to replace the header gaskets and I'd really like to find a gasket that will last a full season of boating. Any suggestions, as you can imagine it's quite an ordeal with triples.

I have a gasket maker who makes me basically a crush gasket that seals very well. They have to be torqued correctly as they help with the usual slight warping of the exhaust flange and cylinder head exhaust flange that can take place over time and especially after an engine overheat. This is 100 percent all USA gaskets made for me.

I had better luck with these in pic below than cometic MLS for exhaust gaskets.
A company in Dallas makes them. they are fairly thick and crush when torqued - graphite material for a good seal especially for slight warped aluminum exhaust manifolds or imperfections on the manifold flange . . .
