Since the valve lift isn’t very high(.580...... assuming that’s the net lift), and the spring rate of the Comp 930’s is also not very high(354lb/in), the 180 on the seat is a little less of a concern.
Even at 180 on the seat, the open load would still be under 400lbs open.

It’s not how I’d “prefer” to have it set up........ but not “unusable” either.

A couple of suitable modern choices would be:
Comp Beehive 26056 - 160@1.800/392@.580 lift
Comp conical 7228 - 136@1.800/390@.580 lift

The conical shimmed up to 150-155 on the seat(about 1.770), would put you at just over 400 open, with a big reduction in spring/retainer weight.

That’s right where I’d wanna be with that combo.
