CHANGING "Lifters"

I had a total of (5) lifters to go bad (stampted retainers) cracked and came out of the lifters. this is second posting.
My question is: will swaping or changing lifters cause a drop
in oil pressure? I have a high volume "melling" pump. Before
changing lifters at 60mph I had 55psi. (at 2400 rpm) Now I have about 42psi same speed @ rpm. the lifters changed were "edelbrock" to "doug herbert" any comments sugestions, welcome. as always hotrodders

Are they an anti pump up lifter? Maybe the bleed rate is high enough to cause a loss in oil pressure. I seriously doubt it though.
