Your oil pressures seem good. Spec is 14psi at idle and 42psi at 2k RPMS @ 80c.
I did my gallery gaskets with the EPS kit (stock ones were still good @ 90k miles). My idle pressure is ~18-19psi, but I've never seen higher than ~85psi even up to redline. Cold start pressure is right around 100psi.
Kind of sounds like the VTC solenoid?
