Alan is ok, he's been emailing me.
The rockers are new factory replacements. The non-adjustables work just fine with careful pushrod length measuring. The lifter preload is built into the pushrod length. I have been doing a lot of builds with factory non-adjustable rockers. They are very light without the adjuster and nut hanging off the back and are beefy enough to handle hydraulic roller spring pressures.
The shafts are new as well and the stands are reconditioned. The end stands are necessary IMO, and come from Precision
Oil Pumps.
