Clutch time. Any advice?

So, the engine has not changed except for the headers. Correct?
I have a Centerforce unit. It is fine, but isn't the same style as stock on the pressure plate. I did have to drill the clutch pedal to help out the worn out spring.
I have had past good luck with MP units, AKA Hays. (Mr. Gasket) Click the url and scroll down to the sub company icons. Click Hays. http://mrgasket.com/
