Cool.

Obviously I too have never used Right Stuff, but thought it might set
up "hard" enough to withstand cooling system pressure, heat etc.

Hopefully I won't have to find out about WBX head resealing and the
like (conversion is imminent) but good to know you've (as others) had
success with JB. A little material and some more time sounds like it's
worth it!
