+1 Not worth the risk.
Once a gasket is compressed it looses its ablility to seal properly, have people re-used them yes would i no.
Can you re-use a condom..sure but why risk it.

Yes they are just be sure to inspect and clean, recoat them properly. And you should be fine. A friend told me that cometic used to say there were reusable but some time ago they stop saying that. So they can sell more.

This is what I remember hearing. I was hoping it wasnt something I "thought" I heard...

Any more people with experience?

I've reused mine three times in almost three years. Twice for a head swap and just recently for a lifter swap. I used carb cleaner and a light dusting of copper spray on both sides of the gasket.............

Why would you not be able to use a cometic MLS gasket but its perfectly fine to reuse a GM MLS headgasket?

i would never reuse a headgasket even if it was made by GOD himself. Every gasket will compress some when it's torqued down. Sure it may work just fine sometimes but the time that it leaks you will say to yourself "****! now I have to tear it all back down again to put new gaskets on? I like working on my car but not that much.

I've reused mine with no issues. I cleaned them up, inspected the coating, and reinstalled dry. There were no spots where the coating had lifted and stuck to the surfaces, so I didn't bother with the copper coat.

Im guessing you dont have any experience with these?

So Ive noticed tons of people saying yes (whove had experience) and a few saying no (who have none)....

The choice is becoming easier and easier.

i havnt heard of anybody reusing the GM mls gaskets. infact, they have some coating around it on both sides that comes off when you remove the heads.

I have once. I changed the heads on a car for a kid in town that had these gaskets. He said to reuse them so I did. Not sure if they held up or not because he sold the shortly after. I just noticed that the gasket looked thinner from having them bolted down before. It didn't look good to me but that's what he wanted. I did tell him if they leak don't come cryin to me because I wasn't going to change them out again. I've also read alot about the Cometic gaskets leaking even when they are new so I figured if they tend to leak new then just think how they would be the second time. Who knows for sure. Sometimes it works and other times it doesn't.

I replaced my head gaskets with a new set when the heads cam off over this past winter.

I did not want to remove the heads a second time! So it was my little insurace policy.

I have reused the MLS gaskets that came on my car, no problems here! If you haven't heard of anyone reusing MLS gaskets you haven't been listening.

Also guys who have used cometic gaskets, are they supposed to be used with a decked block? Ive been told that they are specifically made to be used with the ultra flat surface of a decked block and are a 50-50 shot with un decked motors. This is why I stayed GM MLS, that and they are 30 bucks a pair...
