Can't help you there. Did you try heating the rocker shaft in an onen and
also freezing the plugs? Knowing the measurement of each piece would help
figure out how to fix things. Assuming an "interference fit", the plugs
should be about .002 _smaller_ than the hole in the shaft. If not, then
you'll need to produce some "magic" to get them puppies in there.

The crank end is "bell-mouthed"?
I'd get another crank, if I were you. Have you had this crank crack
tested. If the crank has taken enough of a shot to distort the end of the
crank, I'd question the integrity of the piece.
That having been said, have you tried "dressing" the end of the crank with
a file to help the parts fit better? Does the crank "snout" run true?
I only mention all this because I've made an interesting observation on
the last two engine jobs that I've done... the new lower gasket kits that
I've purchased (labelled "conversion set, 2000, 2.5L) has a really thick
gasket for the front engine plate. By really thick, I'm talking over .030
inches. The original was more like .015. The problem with the thicker
gasket is that you need a pile of the .004 adjusting shims to get the
lower sprocket on the same plane as the camshaft sprocket... like 6 or 8
of them.
This was never a problem not that long ago. So far the suppliers seem to
be unaware of the issue this causes, but I dare you to try to get the .006
shims anymore (at least from TRF or Moss).
Just thought I'd throw that out there for discussion...
