45-50 lbs on the rocker stud's . I'd use blue Loctite on the threads . If I remember right , the Autolite 353 is a good plug to use .

Just be sure to get your heads checked, I put a set of 461's on mine and wrecked the engine, dropped a valve, after the cylinder filled with water.

When I was calling around looking for a replacement head, one on the machine shop's mentioned that he throw's away 1/3rd of the 461's he gets. Because they are cracked.
