I bought a used set of Houser longtravel +3 a-arms and there in the process of getting rebuilt. Along with replacing the lower ball joints, the bushings and plastic sleeves were pressed out for powdercoating, no needle bearings. Dont houser a-arms use needle bearings? Can my a-arms be updated to except them or where they supposed to be there in the first place?

You have the early style arms, which do not have bearings. You can't machine them to accept the bearings, just use new bushines and you will be fine. I can get them for you, have the balljoints in stock with spacers, and can get the bushing in a couple of days.
