John,
You should have no problem using the original or Moss 'long" pushrods. But
why buy new pushrods? Check eack end of the pushrods to see if they are
loose, if loose, clean, compress and tig weld the end to the tube.
Adjusting screws will almost certainly take up the small amount shaved off
the head. Short or long adjusting screws will work as you are in fact
shortening the screw/pushrod combination by 0.022" to accomodate the head
shaving. Bugger all.
I would not use two head gaskets unless trying to reduce compression ratio
( which you are not ).

John,
Be of good cheer. When you get the rocker assy back in place you can
figure out the necessary length of pushrod. Once you know that, it's easy
to shorten a pushrod. Pushrods are really push-tubes with fitted ends.
One end can be pulled off and you use a "parting tool" in a lathe to
shorten the tube. When I rebuilt my XPAG a decade back, Moss was out of
the short pushrods, sent the long ones, and a friend shortened them for
me in a half hour.
