head gaskets for boosted LT1
Not sure what you refer to as high boost but somewhere near 15 psi coppers take the lead. I have my block o ringed with copper and supposedly it will take ~30 psi.
I prefer copper head gaskets, ansd used them even on 12 psi. I have never had a problem with copper and on my rearmount I have run 21 psi without o ringing.
But as it is always said, boost pressure only shows the restriction to boost, rwhp is a better measure. Either way I recommend copper head gasket on three of mine and a few of friends (all >18 psi) LT1's zero failures.
Good luck

o-rings and copper gaskets here too. was running mls but got a good deal on a set of heads and they were already o-ringed. you may waant to consider the o rings with 25lbs but the mls may be ok too.
