I know about Cometics, but would prefer to use something softer with an o-ring setup. What's available?

If your heads have the embedded o-ring, like TEA offers on their heads, then your only option is graphite. Fel-pro should have what you need.

Thanks! I was not aware the 6.0 had a graphite gasket. We will get either the heads or block o-ringed.

My stock gaskets are MLS type. When I changed out my heads to TEA heads, I had to change the gasket material. TEA o-ringed heads have a .041" stainless wire embedded into the head around the combustion chamber. This why you need the graphite gasket. The wire will not press into a MLS type and seal properly.

Where is the best place to get O-ring head gaskets and can i get them for a 3.905" bore??

FelPro has the graphite style gaskets for both 3.905 bire and the larger 6.0L bore:

3.905 bore (graphite) - 9284PT
up to 4.040 bore (graphite) - 9199PT
big bore (MLS) up to 4.100 I am told - 1041

Todd,
So this gasket you said (3.905 bore (graphite) - 9284PT) does have the O-ring wire in it that i am looking for?? Thanks

LS1 gaskets are not o-ringed. You have to have the o-ring embedded into the head itself. It then seals with t he graphite gasket when compressed onto the block. No receiver grooves are needed on the block side.

OK Thanks for that reply. No where do i get the O-rings and how much?? PT#?? Thanks

Brian Tooley at TEA (sponsor) can take care of the o-rings for you. Give them a call! Tell him I sent you

Graphite gaskets and o-rings don't do much for you. Copper gaskets are meant to be used with o-rings, NOT graphite. SCE and Flatout Gaskets both make LS1 copper head gaskets in the bore size that you need. To do it right, the block gets o-ringed. The wire is used on the block, then the heads have a receiver groove machined in so that the copper gasket will compress up into the head, further sealing the cylinder. IMO, you are asking for trouble using a graphite gaket and o-ring.

What does everyone else think??

You risk tearing the graphite when the heads are put on. Then guess what.

Rob Raymer has tested this setup to 25psi with no issues. How would I get teh copper gaskets and what is the price. I can o-ring the block since I am starting with a fresh block. I agree this is the way to go.

Not sure on the price of those brands. I am running a Clarke copper gasket. It runs about $150 a set..Is Raymer using graphite gaskets on top of wire?

Todd, what do you have in the works now that you have sold the formula?

Reckless

Nothin in the works. I am building engines for friends and some others here and there. This setup will be a 408 with D1SC and a cog setup. Just want to make 15psi without issues and do it right the first time. I will likely o-ring the block, but am undecided on gaskets. May try for some copper ones.
