New better cometic head gaskets???

My machine shop says that Cometic is making newer better MLS head gaskets now. He is a Chevy guy. Has anyone seen or heard of them making new ones for Mopars?
Thanks mike

Waiting for mine to be delivered. Don't know if they will be the better ones or the worse ones - since I won't know the difference . They did have to make them for my application - I think. On that subject, is everyone putting them in dry or using some type of sealer?

I use Coppercoat on mine, inside and both outsides.

I installed mine per the instructions - dry and have had no issues.

I don't know how recently these "new ones" came out, but I bought mine a couple months back. I had to special order from Cometic to get the correct gaskets for my World aluminum block. (Hemi)
I was instructed to smear a little Hylomar on the gaskets around the upper water passages and lower center one. Other wise they were dry.
No problems.

Does the deck and the head need a special finish for the Cometic's? Or will just the head surface with a special finish suffice?

I had issues this spring with my cometics leaking water up the bottom three center sets head studs. I noticed each pair of studs were embossed in the same circle as the water jacket, . Each stud should have been embossed separately or the water jacket itself. I called them and since they are so close a rep cam out to where I had it on the Dyno and said that was a mistake on their part and they had to fix the tooling. They sent me a new set this summer but I have not opened them up yet. We took the set off that was leaking and copper coated them and they have been fine since.
