stiff clutch pedal help

I run dual friction centerforce in my race car , it engages nice 6500 to 7500 rpm hole shots are no problem . I just recently pulled the engine to freshin it and the centerforce with over 400 runs showed little wear ( im gonna reuse it ) for my money street or strip the CF is the best clutch out there ....... LOL since when does a clutch have to be hard to engage to be a mans clutch . These clutches are rated to 850 hp as per centerforce , but if you need more they have a dual disc unit that handles over 1200 hp .
