Monte, that's my feeling as well..... But "never say never"

"If" the ex valves aren't tweaked(and that's a big if), then moving the cam a tooth with get the intake c/l close to where it should be...... And then the cranking pressure would be whatever it is.
It's not going to gain 100psi, but at least you'd know what that number was.
That being said, as I mentioned before ....... I feel you'd need at least 180psi cranking pressure to really make good use of that cam. If it's only 140-160 or so(without bent valves), then I'd probably look at installing something a little shorter.

But, I think the results of a leak down test would point the direction on what to do next.

Edit: I just used the Wallace cranking compression calculator.
A 14:1 470 with a 287@ .050 cam in at 108 should pump 181psi at sea level.
Move the cam to 122 and it drops to 126psi, so a 55psi difference.
