KING Engine Bearings?????

I am wondering if anyone here in A/F TAD or TAFC is using or has used King Main Bearings Before?
If so is the XP or the HP bearing been the ticket?
I have been a Clevite "V" Bearing user & like theme Alot but they do not make that main bearing in X-tra Clearance.
Any thoughts good or bad would be appreciated!!

Thanks ITA
