I heard rumors of cometic making a head gasket for cummins. Anybody know if they have them out yet or whether they decided to make them for sure. I thought they were supposed to be out in february. This would be a nice alternative to o-ringing.

I checked their web site, nothing for a cummins

seems to me that they would be advertising it if they had one comming soon.

I am sure you could give them a call and ask

What's a cometic headgasket?

Does that mean that it comes all pretty looking with lip-stick and mascara?

No, but you can put some on it if you're swinging that way! :lol:

Cometic (not cosmetic) is a gasket co. best known for racing apps. The only ones I have any personal experience with was on my CR250 a few years ago. I remember them as being quality units. Got a cool sticker though.

Its still on my welding helmet.

Are they anything special, though?

If they're a potential replacement for O-rings, I would think that they're quite a leap beyond an OEM-style gasket?

It would be a wonderful replacement for o-rings. As far as running a single turbo it would be a cheaper and easier install for supporting over 50psi. Now if you went to twins and were running a lot more than that than I would still want o-rings. Here's a little bit of reading. More info throughout the site. These are huge in the gasser world.

Those are pretty cool! It would be great if they start making them for us guys too.

I had emailed them about 3 months ago about a 12v gasket, they said they were working on a 12v and 24v gasket. They also said look for it in about 1-2 months, but so far I haven't heard anything.

Ok, well I just got off the phone with cometic and they said they have an overvalver gasket in testing right now. But sadly they haven't started on a 12v yet. Also, if the 24 vlave gasket doesn't work then "We're probably going to scrap the whole project". :cry:

He said another 3-6 months and they'll start testing a 12v HG if the 24v one works correctly. This saddens me

The problem with cometic gaskets is the requirments for the sealing surfaces. If you blow a stocker and put a cometic on without machining both surfaces it wont work. They would be awesome for an initial build, but not as a retrofit.

But they're not as good as O-rings no matter what, right?
