Explain O-Ringing To Me Please :)
I know WHY you would o-ring . . . what I'm not clear on is what to o-ring. I've heard of o-ringing heads and o-ringing block. If you o-ring heads, do you also have to do the block? Or is it one or the other? Are there advantages to one over the other?

On my old GN heads and my backup 3.8 race motor(which I still have) I had the heads O-ringed. Basically, a machine shop cuts "O" shaped grooves in the heads which line up with O-ring gaskets-in my case Fel Pro part #1007. The gaskets have a raised surface again in an O shape with some wire type material built in. When torquing the heads down, the material fits into the grooves cut into the heads and crushes to fill the void. This adds a larger measure of sealing and therefore peace of mind. I would assume it would be the same on an LS1.
BTW-I ran between 21-25# of boost back in the day. It held up.

in my case the block will be oringed, similar concept. Since no one makes the type of gaskets Z06Killer is talking about for the LS1 we have to run wire, typically copper wire on a MLS gasket and stainless on a regular factory style head gasket.

Thanks guys . . . now TEA is doing my heads, and he said he is shipping a head gasket along with them. Are you saying that's not enough, that I need wire as well? Where do I get that?
