Springs mismatched

[Mtrain730]

Hey guys I had factory connection revalve my 2012 yz450 last year. I weigh about 175-180 no gear. They said they could make my stock springs work I believe they are 4.7 front 5.7 rear. I am a novice racer. I keep reading from time to time on the forums from some people mostly older posts that the 2010 through I believe the 2013 since I don't think they changed had mismatched springs am I missing some thing should i try some differing spring combinations? Any input would be appreciated.
