lost all oil pressure but not flow

all lock nuts are tight, by correct clocking do you mean the pushrods rotating? if so then they are as the paint has slightly worn all around the pushrod where it contacts the head... which btw doesnt look to severe as its just rubbed off paint but has not nicked pushrod i did have to clearance the heads for the 3/8" pushrods when i built motor, perhaps i should go a little more on clearance? could that of caused the bent pushrod?

yes, clearance on pushrods may be a factor in bending the pushrod, but maybe not THE factor. I haven't worked on a BB for almost 25 yrs, so I don't remember if rocker shaft ends are marked to easily denote lube holes properly like a SB. But if you look at a FSM, the rocker oiling holes on each shaft are at 15 degree angle to the centerline of the shaft attaching bolts. Those oiling hole location is CRITICAL to properly lubricating those adjustable rocker arms. The oiling holes are supposed to favor the valve side of the shaft. If you find that they were incorrectly positioned, you MUST closely examine the bores of the rockers and bottoms of rocker shafts for galling.
