this pump has spring set like the bottom picture
No, it does NOT! The issue is
NOT how the pressure relief spring is retained (gland cap--top or cotter pin--bottom), the issue is the length and shape of the sleeve valve and the length of the relief spring. Since the oil pan is not yet on yours, take the oil pressure relief section apart and you will find it is the Packard design. It
CANNOT be the Olds design. That makes the only sense and your own pictures prove that.

i am not going to drag race, so i think pressure will be fine
Most oil pressure failures reported to me in the V-8 were at
IDLE or low engine speed.
NONE were ever drag raced including my own 1955 Pat which had zero oil pressure at idle, a commonly reported behavior due to the deficiencies of the Packard oil pump
DESIGN.

i could test this pump now, but i want to get it on the road
I appreciate that you have expended time and energy "fixing" your Packard oil pump. But you cannot put lipstick on a pig and have it be anything but a pig. It's much cheaper in the long run while the engine has the pan off and is on an engine stand to buy the Olds pump and adapter kit from Jack Vines and fix it correctly now...otherwise, good luck.
