450 cam in 400 - is this alignment correct (pics)?

I just pulled my '03 YZ cam out of my WR400, and put it in my new WR426.
That looks exactly like it should, and the bike rips and starts easy.

I moved it back and forth (the amount of slack that was in the cam chain before I put the tensioner on) and it worked free.
Then I changed out my shims to adjust the valves in right, re-torqued the cam holder, and it was pretty smooth.
I did that a couple of weeks ago, maybe have 200 miles on it since, running like top, and starting like a dream.

With the stocker WR cam, I could bounce off the rev limiter frequently.
But, with the YZ450f cam, I feel that it keeps strong RPM's for a long time, and never really bounces off the rev limiter like it used to.
It is well worth the time and effort for the starting benefits alone.
