THIS ONE?
<<Joe, about decking TR2/3/4 blocks do NOT . What is the deck height in
the
block with std fig 8 gaskets and liners??? The thin fig 8 gasket route
is
terrible, and who wants to run around a race track to find some one to
shorten a liner, or deck a good block to fit previously shortened
liners.
sounds as if you should consider one of your "extra" blocks considering
the brazing, etc. I assume that you know of the crack problems from
the
short head stud holes. I have run blocks with terrible top surfaces
and
they have worked just fine. The gasket seal around the bore is all
that must be perfect. Why would the factory braze a new block??!!>>

How did you do this, off the top or the ledge?? My machinist says that
it
would be easy to mill .003" off the block sealing surface but he
doesn't
have a 4 jaw lathe to shorten the liners.

Hadn't thought about the "rust" issue. I measured some used copper
ones and they did run about a quarter thou thinner, slightly crushing
to fit. Using the cheap, Vicky Brit thin ones does seem to be asking
for trouble. What do you think about making up some .014" copper
gaskets from sheet stock?
