Cam bearing installation is REAL REAL simple. There is a nice tool made by Lisle that is universal and makse it so a chimp could do it. I've always thought that machine shops were ridiculous with what they charge for cam bearing and freeze plug installation. You can pick up that tool for a touch over a hundred bucks. It can pay for itself in no time if you install some for friends. I always charge 20 bucks. Machine shops charge up to a hundred. Ridiculous.
Here's the tool I have:
