Might be jumping to a 440

[prnstr4life]

I got a few questions as to what i should include into this work.
As of right now i am stock 400 with HMF slip on, twin air filter, alum. airbox with no lid, jet size 170.

I was thinking of doing the following
440cc kit
Stage 2 HOTCAM
FMF powerbomb header
K+N filter
ignition key
rev box (unsure what brand is reliable)
39mm carb
port and polish work

My plan is to search for a spare motor and rebuild that one since mine is new and problem free.
What could all of you recommend for me as far as certain brands, something i am missing, or personal experiences.

the big gun rev boxes r sweet by cousin has one on his 450r is sweet and i heard the iCAT works extremely well and go with the 450r carb since u want to make more power and u need more air to do that also u need bigger oil tank and cooler and run like 110 in it it will also help in the heat reduction.
