Just go to the FAST web page and go through the entire OEM parts section and get every nut, washer, beating, seal, and special bolt or tab known to man. Do every single shift mod you can find on here and cut your trans FOR SURE! Weld your crank. Beef up the clutch and get your self a lock up. Some say you don't really need it but you will be right on the edge, and it's nice to be able to run lighter springs and still have a clutch that doesn't slip. Do the Billit water pump, I'm still skeptical of the Billit gear thing though. But I guess if you got the dough. Do the idler bushing and new snap ring.
Also a few months ago I started an engine assembly tips and tricks thread. Give it a read http://bansheehq.com/forums/index.php?showtopic=152239&hl=
