Checking Ben's web pages (benplace.com) he writes of JB.
http://benplace.com/head_check.htm
So JB is not to be used on the head where the barrel sits? (higher
heat, wider heat cycling destroys the JB?)
If a head surface where the coolant gasket sits has minor pitting, can
the "Right Stuff" be used to fill those voids? Not saying JB isn't
any good (obviously it works) but if one is using RS with a new
coolant seal.....
