Hello , I have an issue and looking for a solution. Installing my rockers on a fresh rebuild with multiple doner reconditioned high lift A & B rockers to make a matching set.( Not sure it matters but ran the B's on one bank and a mixture of A's& B's on the other)... Upon installation I am noticing the rocker's on some valve stems do not center on the rocker foot. Is this normal? If not can I shim the shaft to move the rocker sideways to center the contact point? If I can do this where can I find the shims for this? I have googled this subject with no success..Thanks.
