273 Rockers on a 1971 340

I'm running hydraulic lifters. Took a close look at my purchase.....Shafts and lifters nice with no wear or galling. Tips show a nice shine with no unusual wear indicators. No indication of spring or cup contact anywhere. The shafts do not have banana grooves, and are the type where the end grooves are pointing 1/2 way down (45 degree angle?). The adjusters are threaded down with 0 to 3 threads showing above the pushrods. (I assume this was the other guys adjustment before he removed them)

Pushrods are 7.520 inches total length with .170 cup relief for the pushrod adjuster. As measured with a dial vernier.

In addition, I received a bag of thin shims to center the rocker over the valve, all mounting bolts and washers, and a bag of (15) 7 degree titanium valve spring retainers (for OEM springs and valves). On a side note, does anyone have a single that they wish to sell?
