Copper Spray-a-Gasket

Hi All,

I pulled the manifolds off the '51 300 again and took them to the machine shop to have them milled. The old-timer at the shop seemed pretty familiar with them. (When I walked in the door he gave me a weird stare and first thing out of his mouth was "Packard?").

Anyway, he recommended I get one of the hot-spot gaskets. He told me to use a draw-file to get both mating surfaces as flat as I could, assemble with the gasket then have him mill it. Then he said to attach it to the block in one piece.

Makes sense.

I've got the mating surfaces as flat as possible and there are still some minor pitting on the block-side of the hot-spot. Would copper spray a gasket help? Is it recommended? Or should I just put the gasket on dry?

Thanks,
Dave
