Just asking curious if it can be done I had an issue Saturday made a pass car filled with smoke oil everywhere dead cyl and a pop pop pop used cometic with studs .they held good at 48 pounds I guess 49 was too much
worst part about blowing a cometic is you usually end up with a scoured trench on the head or deck or both , not to mention the stress put on rods .pistons crank and mains that needs inspecting .. thats when your simple headgasket change goes from affordable to time to re-evaluate your finances

The Cometics often will re-seal when the head sits back down and you'll have a running car after the failure that can at least get back to the pits and get itself back up on the trailer.
When you blow a Cometic gasket you can rest assured you have probably killed a piston. The stock ones or Fel Pro equivalent would pop not hurting other parts.
That is the one downside of mls head gaskets. They won't blow like a stock or felpro gasket. You have a meltdown. So you really have to be on your game.
