I have a 351 Cleavland. Bought some bb chevy 1.7 aluminum roller rockers. The original rockers, sit on a ledge with a square post fulcrum that bolts into the ledge, thru the rocker. I want to install the new roller rocker with a screw stud. no problem. But, the new rocker is rounded on bottom, and the top bolt holds the rocker to the stud fine. kinda floating there. Should there be some space between the top of the screw in stud, and the rocker? I can get the screw in stud tight, and the roller rocker tight to the stud, with the special top bolt, but what gap, or distance should there be, between the stud, and the rocker?
am i making this clear?
thanks
