Clutch Out, Which Should I Buy?

[BigIke]

So clutch is slipping in gears 3 and up.

If I'm going to change it I'd like to do it all; FW, clutch kit, short throw shifter, headers.

Looking at
1. 198551 Fidonza FW - 350$
2. DF930140 Centerforce - 675$
3. ZFdoc lockout shifter - 250$
3. Maximizer headers - 500$
4. Henderson tune -300$

Anyone have an opinion on the parts?

Thanks!
Jay
