The question is moot at this point.
I've checked all of the available manuals online and they have nothing on valve springs.

The valves are installed.
All new springs were measured with some very slight variations in height found.
Valve stem heights measured and the springs installed accordingly to match.
-( All new intake valves and the exhaust valves reground).
Spring pressures were tested at open and closed positions and my brother decided that he wanted to bring the pressures up a little so he shimmed all the springs .030".
He estimates that the machine work on the seats and valves took up to .015" from new specs so the net gain on the shims is closer to .015".

So, the final numbers for spring pressures are 56 to 58 lbs closed and close to 122 lbs open. (in case somebody wants to check theirs before disassembly to get a baseline).
