360 swap to adjustable rockers

I just swapped my 360 to a 273 rocker setup:

Stock 273 adjustable rockers
MP adjusting hardware (locknut style) #P5007444AB
MP chrome rocker shafts #P4510636
Crane pushrod set from Summit #CRN-69691-16

I did need to clearance grind the ROCKERS on the underside where they face the valve springs, due to a slight interference issue with the larger springs I have. But there is LOTS of meat in that area of the rocker arm. Mostly I was grinding off the casting seam.

I have a .450/.475 Herbert E3N Hydraulic cam and lifters, and 596 heads.
