MLS Head Gasket? was created by VTEC
It looks like Cometic has discontinued (I think) their composition gaskets that are known to leak. And are now pushing the multi layer steel version. Wiseco is including the MLS with their piston kits.

Does anyone have experience with the new MLS gaskets holding up? I know you need much smoother deck surfaces to get a good seal than composition.

MLS is almost the defacto standard these days. The industry wouldn't have gone that way if they were crap. I wouldn't worry.

I know. Been using them for years in OEM applications, but aftermarket stuff always worries me.
