Checked the oil pressure at the head and it would only get to about 400#

Replaced the HPOP , runs good now but has extended crank time , will start rite away after shutting off but let it set for 5 min. and it takes awhile , the fuel pressure runs at 55# when shut off it slowly drops down to 20# , cleaned the screen (was almost plugged) . should the pressure drop like this ??
