I'm almost ready to fire up my 64 Fury with stealth heads and a sommit ignition box on a 440 engine.What would you use to lubricate the spark plug threads-what is a good starting gap for the plugs.My motor is supposed to make 500 hp. 440 source sold me the Champion RC12YC.Either hemi-itis or superstocker preferred the Ngk 5672A-7 plugs because of the electrode's falling apart and hitting the piston ( I know they run crazy horsepower) I'm thinking I should get the NGK plugs.I've bought 4 dipsticks already=what's 2 sets of plugs? Thanks
