The problem with these engines is cam bearings...I wouldnt go so far as to say its "common" for them to spin a cam bearing after a cam swap... but its certainly a weak point.... more than anything else on these motors.
If the engine has been serviced correctly with the right oils there should be very little wear on the cam bearings and no problems, provided you dont scratch the bearing during the cam install.
.... a poorly serviced engine (even if its relatively low miles) is much more likely to spin a cam bearing when installing a fresh cam onto those old bearings.
I'd check the old cam journals and bearings for excessive brass showing and wear before putting the new cam in.
