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.
