New Clutch and Flywheel HELP!

I had my motor rebuilt by Physixx AKA Ken about 2 years ago. When we took it apart he suggested that I replace the flywheel and clutch. The reasoning behind it was, that since I had everything apart it would be easier to do. Unfortunately due to some exigent circumstances and low cash flow I was unable to do it at that time. Ken suggested I replace the clutch, flywheel, and pressure plate because of the newly added horse power. The other reason for replacing parts was the clutch was worn and 2 of the fingers on the pressure plate appeared to be slightly bent. As far as I know the only problem with the flywheel was the added horse power and the fact that it was the big heavy original one.
