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.

Makes your engine into a bettery and the heads are the anode. Really cleans the water jackets.
 
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.
 
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'.
 
H&H flathead also recommend copper gaskets.i have them on my flathead with a good anti corrosion product in my coolant and have never had a problem
 
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.
 
thanks guys i thought it strange as they were alright in the ol days but now everyone seems to think they are not trev
