Very interesting, Mike.
Yes, let's see how your experiment using
the more slender stock pushrods works
out. Bet your guess on this is right.
Just a thought, sir. The oil pressure on your "new" motor is bound to be
high due to relatively "tight" clearances.
You might consider installing a MiniMania
(maybe Phil has one of these lying about at APT?) oil pressure limiting
MAY allow you to use the thicker Isky
rods by limiting the oil entering
the head via the valve gear, without having to "return" to the machine
to enlarge bores?
