Cometics are MLS and require a specific finish on the block and heads. Mine does not have that finish and everyone I've talked to (Cometic and engine builders) say they won't work properly. I have been known to 'lap' by hand bad surfaces with a good long hand file for ...20 some years and never had an issue. If you choose to run cometics.

I've use the ICE Titan, the ones with the built in O rings, with great success on blocks with no receiver grooves They where all thicker than .042 though I did use 2 or 3 coats of Copper Coat as a sealer also
