its higher because of the spark plug boss is closer to the valves and extrudes into the chamber, not set in the chamber on e7's. so that would mean that the valves are in the same spot as e7's- pushrods are the same length , valves are the same length and rockers are the same. if any of these were off it would throw the geometry off for the rockers.
