Very interesting; you have a '73 cam housing on the right(the bearing sizes were 0.001" smaller than the later housings.)
There used to be galling on those earlier housings which was really caused by lack of oil(leaking from the cam covers) rather than too tight a clearance.
I was wondering about that difference, assumed it was supposed to be like that. I'll see if I can pick up a newer one for the rebuild. Are they the same otherwise in terms of intake and exhaust?
