I've had success using Kopper Kote (I think that's their funny way to spell 
it.)  I cleaned the gasket and top of the block first with lacquer thinner and 
let it dry.  Then I hung the gasket by a coat hanger and gave it a thin coat on 
each side.  I let it dry for about 15 minutes and did it again.  I repeated 
this until I had 3 coats. (wear a mask while spraying)  Finally, I placed the 
gasket on the head (without the studs, then hand threaded each stud (ARP) into 
the stud holes.
