I hate leaks...b

SB chevies have 5 head bolts around ea. cyl. just as BB Mopars,the only really good feature they share,they also share many other design features that are undesireable. SB Mopars have only 4/cyl., and can tolerate 15psi of boost w/only Hi-po Fel-pro gaskets for a decent stretch as long as you're not experiencing lean or detonation conditions, at which point the pistons may give up first. Copper head gaskets w/o any sealer have been used & re-used by annealing then simply placing back in service forever, but they are usually in a small air-cooled sports/industrial app. where coolant passages don't exist.

I was going to say, Just from reading and no practicle experience that for a street slant six, getting water in the oil may be the issue.

Yes, I recall seeing air cooled engines a lot when Googling copper head gaskets, that makes sense.

It also isn't one of those weekend swaps you do where you pull the head and change to the copper gasket. It requires a very flat surface on both the block and cylinder head requiring a complete engine teardown and a trip through the machine shop. So this isn't a spur of the moment upgrade. It requires planning and forethought. Its only when you don't follow the required steps of engine machine work and prep that you have water leakage or seeping issues.

I get it, that's why I'm shying away from copper for my application. It sounds like a big investment in time and energy.
