Re: copper gaskets
I prefer the Best brand of composite gaskets for aluminum heads even on my blown 9CM Merc motor. Do a google search for Best gaskets.

Re: copper gaskets
If you use a good anti-corrosion product in your coolant, you won't have a problem. Also need to refresh inhibitors periodically. There is only a small amount of copper exposed to the coolant at any time. As noted though, the Best brand composite gaskets are excellent. They have gone up in price considerably. Just paid $75.00 for a set of big bore gaskets from Speedway.

Re: copper gaskets
If copper head gaskets are no good why do Edelbrock recommend them for their alloy heads? The installation instructions that came with mine state, 'For #1115 use Felpro #1055 (right) and #1056 (left) copper sandwich gaskets'.

Re: copper gaskets
Yes, copper faced gaskets are OK with any type of head material.

Re: copper gaskets
Dissimilar metal corrosion can be a problem but that's why they made products like Copper Coat or any good brand of silver aluminum pigment paint to coat them with before installation. The paint also acts as a sealant for the imperfections the copper won't mush down into at the heads are torqued.
