Hello Jim,
 
Just wanted to let you know I'm 2 for 2 now on my 345's. When the freeze
plugs are rusting through the head gasket is about to too. So I'd at least
pull the heads and put a new gasket in there before damage occurs. This
assumes the heads have never been off and you are using the factory steel
gaskets.
