HELP!!!273 rocker shaft and rocker install

there is no right or left rockers with the 273 rockers...

what kind of springs and retainers are you using?....if they are stock then you should have no clearance problem...if they are not stock ..then it has to be checked...

as you are tightening the shafts down...guide each pushrod on to the adjuster on the rocker...

as said above some lifter are going to be on the nose of the cam..and the pushrod is going to be sticking way up...as you tighten the shafts..that valve will open...
