I know what they will say. "Buy our springs and install them".
And looking at the specs, I would agree. Too much spring pressure for
the cam.

Exactly, and it isn't because they want you just to buy their springs. A
lot of metallurgy and engineeering goes into designing cam lobe profiles and
pressure of the valve springs is one of those factors. The springs in those
heads are not far from Comps advice but why risk hurting a lobe?

what about the coil bind ratings. 1.500" versus 1.130"? That is quite a
difference.

Yes there is a difference but the lift of the cam at the valve was something
like .490" or so. The springs should never even come close to anything like
a coil to coil contact.
