Intake: 1783 Exhaust: 1457 Head cc: 49.5 Rocker Ratio: 1.6 AFR 1399 Intake: 1900 Exhaust: 1600 Head cc: 58 Rocker Ratio: 1.6 Edelbrock 60217 heads (stamped NHRA Accepted) Intake: 1900 Exhaust: 1600 Head cc: 60 Rocker Ratio: 1.6 If valves have to match stock +.005 like the rule book states, then neither of these heads listed as SS replacement heads in the Stock Car Classification Guide can be used without basically remanufacturing them down to factory specs. Why would NHRA approve heads that come either supplied or ready for valves that are too big? Some posters on this forum make building for stock or super stock way too complicated. I refuse to be deterred. Dale Chris1529 I have so much money under my hood I can't fit my engine.
