i just put my AFR heads on i am getting ready to put the roller rockers on to tighten down the first one but it seems like there is not enough clearance. i mean when i screw it on the top bolt it seems like 1 turn and it is at 0 lash could this be right. it does not look tight....

 

There is a flat side and a round side where the nut screws down on the rocker arm make sure you have the flat side up. Also make sure you have the jam nut screw all the way up to the top.

 

so how much clearance will there be as far as from it screwd on to the top of the stud?

 

Have you rotated your motor to make sure each lifter is on the cams
base circle before installing the rocker?
