Cometic gaskets

I put mine on my 408 as instructed. DRY. But on my current build I had my offset pushrod heads on and the Indy intake sucked oil twice and had gone through maybe 10 heat cycles. So I removed the heads, drilled out the rivets, carefully cleaned each layer, and sprayed them lightly on each side with Hi-Tack. As always I cleaned the heads and block with laquire thinner. This is the second season on them with zero issues.
