[TR] tr-3 liners

[Tony Drews]

Sealants add to the deck height - using a minimal amount and having 
something that is isn't a thick compound helps.  I use gasgacinch, 
mainly because that's what I also use for the head gasket.  It's 
pretty thin too.  You can pretty easily make your own figure 8 
gaskets from brass shim stock in whatever thickness you need - that's 
the easiest way around the issue.  And you really just make 4 o 
shaped gaskets, they don't need to be figure 8.  You can cut them out 
with common scissors (carefully).  You may want to try assembling the 
head to the current assembly without a gasket and torquing to 40 lbs 
or something - there's definitely a very slight chance that they will 
further compress.

Do the alternate lower gaskets before looking at altering the 
liners.  It is possible to shorten the liners slightly - the best way 
is emery cloth taped to a piece of glass, swirl the top of the liner 
on the emery - kind of a fig 8 pattern.  Impossible to undo, and easy 
to get one side shorter than the other, then you're looking at new liners.
