Narrative:

On takeoff roll, noted that #2 engine had to be nearly firewalled for takeoff thrust, then EPR dropped slightly at 120 KTS (V1, vr 139/141). Other gauges looked good. Continued takeoff. Noted on subsequent climb and cruise that egt was at respective limit. Suspected bleed air leak. All anti-ice valves indicated closed but there was heat in cowl duct as indicated on temperature gauge. Passed word to company maintenance, and followed stuck open valve procedures.
