IMO King bearings are "rebuilder" quality bearings .When you buy an average priced "rebuilt" engine a lot of times they will have "Kings" in them ...They are inexpensive and work ok in non highly stressed engine ....I normally use Clevite...The series ,depends on application.....M.O.
Also, a lot of high horsepower forced induction engines start out with a king because they are more forgiving when you have a bad tune-up. Once the tune-up is right they sometimes rebuild with a H bearing.

Not to start a bearing debate. Because I think proper setup is key. Straight mainline/ cylinders and proper clearance. But I've used Kings with no issues. Every time I pull the bearings out they look new along with crank journals. As far as plastigauge goes. That might b ok for a stock automotive rebuild but past that I don't think so. To much margin for error and it's so much faster using a dial bore gauge. Why in the world would you use plastigauge?
Looking Back at his original question - he is rebuilding a STOCK 502 engine. No supercharger as others referenced experience with. How many stock 502's go 700+ hours with "P" bearings? Reality, any of the bearings mentioned will work perfectly fine. IMO, tolerance, oil quality and not over heating the crap out of it is more important. If this was for one of my customers, being a stock engine, i'd be more then ok recommending a "P" bearing.

Actually King bearings are widely used in the racing fields from F1 to some of the top engine builders for the dirt tracks. They have a seminar every year at PRI that is standing room only and many performance engine builders attend. I know as I attend their seminars every year. They are big in the racing fields but do not get involved into huge marketing about it. Probable could find a lot of stuff on youtube about them plus some of the PRI seminars because I always see in person they are filmed. Anyways FWIW
