agree with boxtradamus, also agree on ghetto fix. over the years i've had to deal with bad or mismatched cam bearing caps many times, usually with head off which is little easier, but never had one i couldnt make work and last with no problems. they are very close and many times a mismatch as is will torque right down and allow the cam to rotate freely. if it binds the cam, a little 600 sandpaper on your finger dressing the bearing surface will generally get the bearing sized to the cam. may take several times just a few strokes each polishing the bearing rotation wise. head stripped of retainers, springs, valves pretty easy to get cam to spin freely on head. asembled on engine as u, gonna have to get a feel for how engine turns with current bearings-plugs out- and duplicate with new cap. one tight cam bearing can lock engine down or tighten it up turning with wrench. this works, done it several times, even had one ten head the guy lost all cam caps, had a set on a parts head, only had to lightley dress 2 caps and the cams spun freely by hand head stripped, street bike running 2 years now. gonna have to find cam cap though.
