What is the proper procedue for adjusting the valves on a 351c with crane roller rockers? I have heard various different ways to do it. I believe the best way is to put the cylinder on TDC, turn the adjuster down until snugg, then 1/2 turn more? My understanding is that the location of the lifter on the cam lobe is critical. How do you know when the position is correct so you can do the adjustment (whatever that is) Do you have to do each cylinder individually or is there some sort of system that you can follow? Any info would be appreciated.
