Cometic gasket head and block prep Putting my engine back together and I'm using the .040 cometic gaskets. I plan on spraying them with copper, the block is razor clean and the heads have about 25k on them and are also real clean and I also checked them on a bench with a straight edge to check for warpage and found none.
With all that in mind am I ok to go ahead and install them or should the heads be resurfaced? Has anyone done this without resurfacing the heads? I have done this before with fm head gaskets multiple times and never had issues but I was curious about the cometics. Closest machine shop is a couple hour drive from me and the wait time is horrendous

i think its something that was always done with the old timers or old engines in general and ppl have just carried it over to the newer motors. with a mls head gasket copper spray is not need and advised against using. granted i am from the import world converted but i have used cometic mls headgaskets on many high hp 4 cylinder apps never with copper spray. the outter layers of a mls gasket already has a coating on it. not saying it will not work with copper spray but def not needed.
