Speedmaster Stainless Rocker Arm Issues

mshred said
My last LA builds used Hughes and T&D rockers and I shimmed them as necessary, so I am well aware that rockers are not just a bolt on and go item. However, I am just wondering how much "shim" per say is needed with these rockers and a dual valvespring setup, as I see it there is a big difference in shimming for geometry vs shimming for interference..

This will vary on the blocks height, gasket used, head milled or not, actual placement of the fulcrum point, rockers placement of the tip and adjuster end and where the actual placement of the ball or cup end is, valve spring dimensions and there placement on the head in relation to the rocker arm and finally, the camshaft itself.

Fun fun fun…..
