I haven't tried the K&W Copper Coat gasket coat on the head without the metal gasket in, but I use it on the intake port and about to try it for a better fix for the CNS carb air leaks.
This stuff is a "Universal gasket compound. Once tacky, resists water, steam, gas, oil grease, anti-freeze, solvents..." bla bla bla.
I have the metal can with the big useless fluffy 'dabber' attached to the lid inside. Just use the waste end of zip-tie to apply then toss it ;-}
