Please read my bearings

I bought the motor used, mostly because it had a 904 trans attached to it and I needed the accessories for a Magnum project I'm working on. Looking at it I kind of figured all that, as I said earlier, I have just enough stored knowledge to be dangerous. A couple of the cam bearings were wiped as well and the oil pump drive was pretty stiff to say the least and had to be driven out. It seems as though someone worked on it and forgot a few steps along the way.
Thanks
