Hi Brian
Your core should be fine as long as you use a low pressure cap on the
radiator, don't use one of those 13 or 14 lb caps they sell for late
model systems.
I have the same situation as you and I believe that I am running around
a 7 lb cap (relying on memory here) and I have had no problems with my
40 yr old heater core.
