 Paul,  you may have been wondering about the lower water pump neck.
 As soon as I can find the time, I am going to make a weld on adaptor
 to convert it to 1" pipe as well.    Jerry

One inch Pipe or one inch AN hose? There is a large difference.
One inch hose is one inch but one inch Pipe< [tube]  is really about
1 3/8 inch with close to twice the area and flow.

IMHO one inch hose is a bit marginal. I am going to use Wiggins
couplings like Bill Schertz  and Continental uses on their liquid cooled
engines with 1 3/8  OD tubing.

One inch pipe has a bore of one inch. One inch pipe to one inch AN
fittings are available from C & R.   I based my decision to use one
inch AN fittings  on several considerations. First even though
standard rad hose is much larger, the thermostat is a major
restriction that every stock cooling system functions with.    The
racers I talked with at SevenStock  replaced the  thermostats with
either 5/8" or 1/2" restrictors.  I asked Griffin for a
recommendation for AN conversion and they said one inch.   I want and
need the ease of routing one inch hose.  However,  I am not saying it
will work.     Jerry
