Setting adjustable rockers About to put the heads back on my car. I have comp's 1.85 adjustable rr's.

Figure out how much one full turn moves the adjusting screw.
Adjust the rocker for "0" lash.
I use a felt marker to put a mark on the roller then adjust to the point where I can't roll the roller with my finger.
I use that as "0".
Then I just dial in the preload.
On mine (Comp Cams #1500) one full turn = 0.050"
