Re: [Amc-list] leaky Nash head



I've never seen anyone spray the head and block, just the gasket.
Years ago I was also told you could use silver header paint on a head gasket as it was like 99% aluminum or some such high concentration.  I have no idea if this is true or even if you can still get silver header paint! I know the story tellers said they used it.
  I always used copper spray. Dad used the gloppy permatex in the bottle with a brush.
