Cam swap cause Oil pressure change?

Fix the leak 1st, that's where you start.

My exp w/relief valve issue were always stuck at a lower psi, typically.
Like no more than 20 psi no matter rpm.
I did replace the gasket at the filter plate and it was fine until I rev'd it and the pressure pegged the gage, started leaking again. it won't hold over 100 psi I guess.
Something is causing excessive high pressure maybe a blockage somewhere in the oil passages.
