225 Slant six Rocker Arm Adjustment Screws?

How many do you need? I have some good used. Also have some NOS rocker arms.

Was wanting 12 in a set, just to replace them all at once. One of my friends just now told me that he knows the owner of a machine shop, so if the heat-resistant loctite doesn't work, I'm sending one of the good screws in to them. Thanks for all the offers though, I may pm someone if both of my current plans fail.
