Re: Head gasket?
Best #509 is available as a copper or composite gasket, same part number. I prefer copper because when and if removal is needed, the comp is a bear to get completely off. Other racers that I know use the composite, saying they have better luck with it. Copper seems to require torqueing more often when new than the comp. Like Katy, I use silver paint, a light coat, let dry, then a heavier coat dry until tacky, then install. Copper coat never dries, so is a bit slippery, paint acts as a glue, so is more apt to stay in place.
