535 supercharged first time start up?

I pulled the valve cover off of the passenger side. I am able to pull the lifters up through where the push rods go in the head.on a big block. Without removing the intake. I've got three that are partial collapse collapse. And one that lost all of its prime. It's one of the three I can't get out of the bore. The magnet pulled the rest out. The two that were partially collapsed I was able to put in oil and pump them up solid. The other one. I have to wait on a lifter removal tool. Not sure why it's that stuck... I'm hoping it's not beat up on the end that's keeping it from coming out..... Is there any possible scenario that it was just lifters not pumped up all the way for whatever reason ? When I do the lifter across the bottom of another lifter there is just barely a concave on the lifter bottoms. On the lifters that I did remove the cam looked nice and clean. I'm searching for a silver lining here lol
