Mate, looking at doing this to VT Clubby, what did you pay for them, and are they a direct fit to the standard heads?

have a look at this mate there is a video of a comp cams representative installing adjustable roller rockers... pretty sure they'll be the same

when you say "bolt straight onto the head" you mean shaft mount? do the intake and exhaust have a bar joining them?

if not adjusting is easy. if you are doing the intake valve, rotate the engine until the exhaust valve starts to close, then graba poushrod and rotate it back and forth with yoiur fingertips. tighten the adjuster till it just grabs the rod, then stop. do that to all of the vlaves then start the engine with the rocker cover off. let her warm up to operating temp then tighten each one to the point where it just stops tapping and you are done.
