Clutch Release Fork

[LANDC]

I have'nt ever paid much attention to the clutch release fork in my truck before. But today I was crawling around listening for problems and fine tuning when I noticed something that seemed out of place. The clutch release fork was dancing around while the engine idled. I recently placed a new centerforce dual friction clutch between a 465 and a fresh 454. The throughout bearing is a centerforce bearing. I meticulously assembled the flywheel, disc and pressure plate to ensure it was done correctly. I am curious is this normal for a throughout fork to move around? -
