Just got off the phone with Pat in the tech office, his quote was "machining the rocker bosses on the head is NOT legal". Milling the pedastils to accept a screw in stud and guide plate would be the only way to locate the pushrod using the OEM style non railed rocker arm. Not really the answer I needed to hear but that is what NHRA tech told me. How can I see a copy of that email that you have?
Thanks again
