I have a 390 Stroker that I'm trying to complete. I've ran into a problem with the EQ Iron Ram Heads (1.92/1.60 valves). Due to the cam, Odessa Heads installed .100 Valves and stronger springs. I purchased Hughes 1555 Aluminum pedestal mounted shaft rockers for the heads. These rockers are designed for stock valve stem lengths, are only adjustable on the pushrod end, and thus geometry is off. Installed without shims the rockers ride on the outside edge of the valve stems. Playing around, it takes .240" of shims to correct the positioning. This seems like an awful lot of shims and I'm hesitant about moving forward. Should I replace the Hughes rockers with adjustable stud mounted ones? Or should I shim the Hughes rockers and move forward? or third option is finding bee hive springs with required seat pressures and stock valve stem lengths. Thanks for any input.
