The good folks that have chimed in here have solved their issue of=20
getting the wet liner TR motor head gasket to seal. There are many=20
solutions that work, but the important thing to realize is there are=20
variables to each solution. It's like each head gasket has it's own=20
recipe for success. Choose a head gasket and follow the recipe to the=20
letter and your head should seal just fine. Some recipe's are easy,=20
others require much more diligence. The crux of the issue is setting the=20
liner protrusion to the right height for the gasket being used.
Composite head gaskets will hide a multitude of sins when it comes to=20
liner protrusion, but may be hard to find a quality one that matches=20
your head, plus in theory they may not last as long and may not be as=20
robust.
Solid head gaskets require very tight tolerances on liner protrusion,=20
are more sensitive to techniques with sealant, and in my experience can=20
be a real pain to get the head off! (Thanks Bill!!!) But when used=20
correctly should be more bombproof than composite head gaskets, and you=20
can order the exact thickness you desire to meet compression ratio=20
requirements.
Bottom line to any new guy... Do not fall into the trap of asking 10=20
people what they do, then pick and choose steps from different=20

Worked for me, just sayin'...
