Man,
Go with whatever the place you're tuning with recommend.
So many varying opinions. If it were me:
- 460 fuel pump. Add drop in GFB fuel pressure reg
- no bov
- wouldn't waste money on btr. Just accept limitations, and upgrade to something else if you're going to build a transmission
- suspension bushes, shocks, ball joints etc
- brakes. 4 piston Brembo front, PBR rear is best value
