Lou,
You might also consider a high flow thermostat. A lot of the common modern
pellet style thermostats do not flow the same volume as the originals. Look
for one from Robertshaw:

You shouldn't need to resort to an aftermarket part if your original pump is
in decent shape.
Make sure the hoses are in good condition and not collapsing, choking off
the flow.You should be running a fan shroud to ensure adequate air flow thru
the core, and the hood should should be sealed to the top of the core
support to keep the heated air from recirculating through the radiator
again. I wouldn't worry too much at 200 degrees as long as the water stays
in there, new cars run at least that hot.

Last year, I had my radiator recored (3 or 4 row...can remember which), and
upgraded to a 6 blade fan, but the temp gauge starts to creep up pretty high
and pretty quickly on a hot day in slow traffic. I hesitate to go from a
180 to a 160 degree thermostat. The shop used a laser pointing temp gauge
which shows that the thermostat housing area is indeed staying right around
180 degrees, but when you point the thing a little farther back, and on the
intake, and areas near the temp sender, sure enough the temp is in the
200's. Dunno what it should be in those areas, but it just makes
uncomfortable thinking that it could be running hot.
Timing is OK, new cap, etc. I see that Summit Racing sells "FlowKooler
Mechanical Water Pumps." Anyone have any experience with these? Wondering
if they work and are really any good. Here is the narrative from

Get 30 percent extra coolant flow.
FlowKooler water pumps solve low-speed heating problems by doubling the
water flow rate at low RPM and idle. At 3,500 RPM the flow rate returns to
normal to prevent too much water flow at high speed and they last longer
than a stock replacement. These pumps use a specially designed steel plate
on the impeller that traps water, eliminates cavitation, increases flow, and
reduces engine temperatures.
