Al,
Too true!!
For P-ports the local chaps are actually welding in the port tube to the Al housing from inside the water jacket and has so far eliminated the eventual leaking into the port problem associated with P-ports. Just finishing off the filling with JB weld
I'm yet to try it.

On another note, has anyone contemplated using the two part puttys in areas
like intake manifold construction.  I saw some in HD that claims good for
temps up to 450.  I'm hesitant, but this stuff seems to be a cousin to JB
Weld.
Bryan

JB weld ( and similar) is wonderful stuff that adheres to almost anything,
and is amazingly strong.  So if need things to hold together and make a good
seal - great.  But if you need real strength, anything that just adheres to
the surface is not going to be as strong as a good weld.  So consider your
application, and what it has to do, and then decide.

FWIW,

Al G
