Quote: I seem to recall those heads needed special rocker arms (exhaust side only?) to extend the pushrod towards the lifter valley. You might want to grind the pushrod clearance before doing the rest of the machining in case you grind into the water jacket and ruin the wedge block.
Ya they run special exhaust rockers. IIRC they are only 1.4 ratio as to move the pushrod far enough in.
