You can go with an aftermarket clutch line also as that might help. I recently blew out my clutch. Clutch disk broke and torsional coil springs at one location dislodged. Cost about 1500 dollars with 680 dollars being labor. I put a centerforce dual friction clutch in, along with new oem flywheel, ford racing pilot bearing, and new oem slave cylinder. Well I did also have the mgw shifter arm bushing installed also. The high rpm shifts do not appear to be an issue now and my clutch pedal is softer. However I have not really put the new clutch to the big test yet because still trying to break it in easily and can't afford to replace it again so soon.
With your amount of hp you may want to consider a Mcleod dual disc clutch or equivalent.
