1.6 Rocker Arm Install , Lube questions

Yes they are 440 source rockers. I will be installing all new parts except hold downs. Trial fit of driver side shows .200 inch clearance, good position on the valves. Until I set lash, I am not sure about the thread of the adjuster. It looks like it will be flush with the bottom of the rocker or maybe, 1 thread showing. Tomorrow I will install passenger side and set the lash. As to the shaft, they are supposed to be hardened, evidently not. Depending on if the track opens next year and how many runs I can get in will determine how urgent I will be to upgrade..
