    You really need to measure. Everyones setup will vary and the little differences can makes up for a noticeable on on pr length. if you go with the wrong length you can have a noisy valvetrain all the way up to the valves not opening or closing fully, for the 20 bucks it costs for the measuring tool its best to do it
