6 psi should be more than enough pressure, 7 psi is about the most a Holley type needle/seat/float assembly will handle without fuel getting blown past it.

Liquid-filled guages are notoriously sensitive to heat making them show a false pressure drop read low, I never trust them to read right warm. Once pressure is set cold there is really no reason it should change when warm.
