Well, I know a good number of engine builders in southern Ontario ... and none of them will use Cometics without the proper finish. Anyhow, if you're going to offer advice you should probably err of the side of caution. No doubt you'll get the last word in so as not to loose this debate but I've said my piece.Yes a retail customer disclaimer. For DIY'ers.
I agree. Proper inspection of the surface is important.Well, I know a good number of engine builders in southern Ontario ... and none of them will use Cometics without the proper finish.

For sure, I agree. But what is most important (and I guess I should have said more bluntly to start with), is the root cause of the damage must be located and remedied. This is way more important that WHOS parts you use to put it back together with. Many good tips passed along by the members here, but you've got to know for sure what happened in this unusual situation.Why not use head studs?
Welcome. The fact that you indicated the engine got hot a few times could say something about the gasket failure. Check surfaces for warpage first. What bolts are you using ? What did you apply to the threads ? Did you use proper fastening/torque technique during installation ?
They are stainless steel, which is very tough, but a head gasket is also supposed to conform to slight irregularities as well. The makers of the gaskets require a very smooth finish, because of the fact that stainless steel is so hard it does not conform. Old muscle car engines were not machined to the spec required. Multilayer steel gaskets were developed because of the scrubbing action of an aluminum head on an iron block. Back in the 80's and 90's I changed enough head gaskets to put my kids through college for that very reason.They are all-metal. No composition to "decompose ".
There will always be talk about surface finish, but in reality, they are a 3 PC steel shim gasket. With a better sealing surface than the originals.
Just about every BBD at our track uses them with or without deck resurfacing.
I've used them, re used them, and re used them again.
Would have to be a pretty rocky deck surface before I say no.
Did up 440 not stroked,but similar build.Was the blocked decked when you built it or just bored? Cometic need a specific deck and head surface finish to work properly. If you didn't have this finish done, forget about Cometics. For Trick Flow head bolts, call ARP directly - they know their **** and will help you out.
