cam shaft 284/484 and new lifters

the 800-16 are not the right lifter numbers and why does it have adjustable push rods for a hyd cam ? just saying alot of miss match parts
those lifters and push rods were the ones that were in the 360 engine with 284/484 cam, I am assuming my engine builder had that box setting around and he put lifters in it, just a extra box for storage I guess! I never thought about the numbers showing on the box not being the right numbers! good catch! so that would means that I am not sure who made the lifters, just that they were the ones in the engine when I got it!
