Tom, the stock HG is good to 20psi and then some...lasts for 150k-200k+ miles...
easily available...comes in a reasonably priced kit, etc. For me it's the best choice
for stock to 300hp.
The copper HG failures are almost always at the coolant and/or oil passages,
not the cylinder seals, which are usually o-ringed like Gary said. Probably
what happens is that an aggressive o-ring job (with a lot of o-ring sticking up)
gets mad clamping force around the cylinders, but not much clamping on the outskirts...
hence the leaking.
Now the exh manifold gasket, that one fails on me all the time! I'd like to try the
copper version of that next time I'm in there!
