best header pipe for wr 400

hi guys I have a white bros e series exhaust with a stock header pipe on my 99 wr 400 just wondering if anyone can tell me the best header to use money isnt a issue any advice would be great :-)

Keep the stock header

I would upgrade to the 2001 WR426 header just to get acces to the oil filter. Believe most, if not all of the aftermarket headers fix this issue as well.
