Re: Copper Spray on Cometics?
I put mine straight on the heads and haven't had any issues in that regard. The point of the Cometics as I undertand it is that they need the RA50 smoothness finish to seal properly. Wouldn't adding copper sealant be at best unnecessary, at worst compromise the seal rather than help?

I use the spray if I reuse the gaskets.

Just replaced both cosmetic gaskets on my 602ci big block race engine. I sprayed them with copper spray as did the builder who assembled it in the first place.

My :2cents:? Put on a set 2 or 3 years ago. Reused them once. Ran them clean both times with no issues at all. When the motor goes together this time I will do the same, but with new,
As mentioned surface must be RA50 smoothness and, of course, flat.

Ra - Roughness average, most commonly expressed in micrometers (microns). This is the most universally recognized and used international standard of roughness measurements. It is the arithmetic mean of the absolute departures of a roughness profile from the mean line of the measurement. Ra may also be expressed in microinches.
