04 yz450f cams or 09 yz450f

hi guys,

Im going to do the yz 450 exhaust cam swap. I have tried the yzf timing with original wr426 now looking to rid of the decomp.

my question, will there be a difference between 04 and 09 cams? im thinking the 09 cam as its newer and less hours but would everything still function correctly

your opinions please,

Really appreciated.
