rocker or lifter noise please help

Well I puuled the intake and all the lifters. The drivers side all lifters were solid passenger side 5 were not pumped up. After looking in the lifter bores the driver side has has large holes and you can see the oil galley but on the passenger side, someone has bushed or filled in with bronze all the holes so no oil can get to the lifter. I am assuming this is not supposed to be this way. And that would explain all the noise and why the lifters werent pumping up. Remeber I switched from a solid cam and lifters to a hydraulic. Now what the heck do I do???????
