Default O-ringed block, what head gasket?

I have a stock bore 364" motor and it has an o-ring cut into the block and I want to use the o-ring set up. I was told you need to run a copper gasket but SCE says to not use an O-ring with their gasket. Who else makes a good copper gasket to utilize an o-ring?

we use SCE copper gaskets in our o-ring setups

They do have specialty gaskets which don't use o-rings, maybe they were referring to them vs. straight copper?

I'll be o-ringing my block as well, and I was told by a reliable machinist that the stock LS1 graphite gasket works great.

I just looked on SCE's site and there is only a listing for Warhawk and LSX block. There is a Gen 3 section but it only has intake and exhaust header gaskets in that section.

I guess i will have to do a little more searching unless somebody else knows something.

I understand that, but unless Fireball can show me a part number or tell me where he got his gaskets from, I have hit a brick wall since the people (SCE) who make the gasket don't even list anything on their site for a copper o-ring gasket for a Gen 3 block.

I will give them a call in the morning. To see if they have anything thats not listed on the site.

Its cool. I have been too busy trying to get everything else together to even call SCE. I really need to call them though.

The block on my V6 was O-ringed. I always used the OEM graphite gaskets. There is a steel firing ring on the gasket that the O-ring clamps into. Mine always worked great.

A common problem with copper gaskets is that they tend to leak coolant around the water passages. There are ways around it though.

Here are some other manufactures of copper gaskets

http://www.husseycopper.com/HusseyGa...seygaskets.htm

http://clarkcopperheadgaskets.com/cc.../content/?id=1

Im not a fan of SCE gaskets only because their customer service sucks, If they don't stock them it will take months to get them.

Thanks for the help with those other companies. I also found Flat Out gasket company. They have a copper gasket too. I just don't hear many people using them.

I was looking at the gasket with the 4.130 bore but since my engine has a 4.000 bore I don't know if that gasket will cover the o-ring and still seal the cylinder well enough. I don't see something with a 4.030 bore or something of that nature, unless I'm over looking it.

Ok guys I have been doing some research again on this and I found some old threads on tech. In one of the threads Rob Raymer said he used a Fel-Pro composite gasket with an O-ring on 24psi and never had a leak issue or any problems of any kind on sealing.

Does anybody here use a composite gasket with an O-ring or know anybody who does?

We used an SCE and have been kinda disappointed. The gasket had their "sealing" compound around oil and water and it was peeling off when we got the gasket. Due to time and a demanding customer we got their stuff off and used a sealant and are now having to pull the motor due to coolant and oil leaks. Customer of course feels we should fix it for free

We never had this issue when we had custom copper gaskets made in the past. I am not saying this will be the case every time, but this has been our experience at this point.

That was their ICS Titan or Titan gasket I'm assuming. Its not meant for O-ring set-ups. Their Pro copper gaskets are for o-ring set-ups

Wow! That sucks! Only the Pro copper is to be used for o-ring. The ICS and Titan are for non Oring and they are the only ones that come like that with seals on the coolant and oil passages.

This is true, but it did eventually begin pressurizing the radiator, even though boost had been lowered to 16lbs. We also used custom copper head gaskets and a double o-ring setup with receiver grooves in both the heads and the block (Brian Tooley worked with us on that). But this also eventually leaked. Keep in mind, at the time we were doing this, there were no aftermarket heads available. So I attribute most of these issues to the thin deck surface of the factory casting heads.
