Brian-

Once again, I am far from being an expert about much of anything, but my
IH mentor-Tom Harais-once told me that he thought IH used a valve
("umbrella" shaped, perhaps) that was made to allow a certain amount of
oil to trickle into the cylinder, so that it would be lubricated on
start up.  If this were true, it would keep the cylinders from having
that initial moment of movement with little to no lubrication on the
cylinder walls.  
I saw a later post that spoke of the different types of valves used, and
their respective reasons/advantages, but don't recall specifically.  I
will add that I just got my '68 T'all back a feew months ago from a
COMPLETE rebuild, and it smoked the second I started it up the first
time.  Three mechanics I talked to about this all said that it was pure
IH.  I was afraid that there was something wrong with the build, or that
it hadn't been built at all and I had been robbed!  Unless there is a
national network of IH specialized mechanics set up just to screw me on
this one, I believe it to be true, as these mechanics were in three
different states!
As for the size of my "White Cloud," it doesn't sound quite as large as
yours-the size of the whole bed, but you can see it without straining,
coming from both sides of my duals, I believe.
