Cam Experts: Lobe Separation Angle?

Oregon cam said they could ground to a different LSA, but the LC (Intake or exhaust) will need to change to affect the LSA. My question involves building the highest initial cylinder pressure, so should I change the existing LCs (and consequently the LSA) or will that cam, as ground, build high initial cylinder pressure with the existing LCs?

I think it’s mostly dependent on intake valve closing event.
I just did a dynamic compression calculator for a 360 since those numbers were fresh in my head.
Closing the intake valve 4* earlier builds an extra 5psi in cranking pressure.
I think if you spread the lsa then the recommended icl for the cam moves back a bit most of the time.
