Help with 440 kit mods

[trxPOWER]

hey guys, it looks like i am going to be getting a 440 kit with hd head studs in my 400ex, and i was wondering what is best to upgrade next. Eather exhaust or carb? it already has a stage 2 hotcam. thanks for any help!

Do the exhaust so it will flow better. BTW put up a pic of that stock shorty, i've never seen one

CFM or UM larger oil tank and a spal fan.
