my valve train has been making alot of noise lately, and im wondering if i may have too much gap under my rockers, opposing the pushrods. I tried to set it up correctly, but dont know if the jig i made for my dial indicator moved or not, or if i even set it right correctly. Just so you know, if it helps, i have a Crane 2031 cam, with longer 3.500" pushrods, and im currently using one shim under each roller rocker, dont know which one. thanks guys if you could help.
