I've been considering oringing my 6.0 ltr wire in head with grove in sleeve. I would like to hear about your guy's experience good or bad.

I want something that can run 18psi on e85 or meth without any problems and 23ish at the track. I dont want to have to pull the heads every outing.

or you could wait more than 2 hrs or you can try a search.

Depending on how your o-rings are setup you may have to run a copper gasket.

My motor is o-ringed with the groves in the head, the o-rings are .018 out and require a copper gasket, wich is a head ache within itself. I have been told that if you keep them between .012 and .015 out that you can get away with a MLS gasket.

All the o-rings will do is help minimize the combustion pressure and gas from pressurizing the coolant system causing you to push water. You can still lift the heads and ruin a gasket with o-rings.

Thanks already searched and read some old threads just not sure if this is right for me. So why are the copper gaskets so bad? Doesn't sce make one that seals around the coolant passages?

copper gaskets suck because they weep water, some more than others. From what i can remember a few people have tried the SCE titans and hated them.

My motor has flatout copper gaskets and a healthy layer of YAMABOND to help keep the water in.

Seems kinda like a pointless operation if the heads are just going to lift running over 20psi. This thing will not be seeing anymore then 25psi and I was just looking for something that will be reliable

How much power are you looking to make? PSI doesn't mean a whole lot.

FWIW we have ran just about every head gasket combo out there and have never BLOWN a gasket. Every 4bolt head combo will push water at some point. But that being said... 90% of the people on this site would be fine running GM MLS gaskets.

All copper gaskets will still need some sort of sealant applied to them.

It will be a 370 with Patriot stage3 317's arp fasteners truck manifold kit with a S80 I would hope it will be around 800ish rwhp on pump+meth and closer to 950 on race gas. Shouldn't have to run anymore then 23 psi or so max this thing out?

I guess I'm having a hard time seeing the benefit of orings seem like same problems still occure at same power levels?

You shouldn't have to run that much boost for what your goals are.
