It may not (and probably isn't) tappable without changes to cam timing (as the later engines have with lift), port, cylinder and head design and all kinds of external engine stuff as well. Expecting the simple intake, exhaust and chipping to make anything more than a modest increase in power (at the expense of tolerance to bad gas or excessive thrashing) isn't realistic.
