Just wondering if their is a YZ timing post that tells step by step(ok maybe not step-by-step but close) on this yz timing. And is it really all that, and worth doing to my WR450. :)

On the WR450 you need to buy a YZ450 exhaust cam $160.00 :)

No the intake cams are the same. You will want to mod you air box to allow more air into it. Many here on this forum are putting 1" diameter holes with foam plugs in the side of the box. I prefer to open up the rear of the air box and keep the sides sealed to provide a higher pressure around the filter (like many High performance street bikes) :)
