05 WR450f Timing marks

Hi, I'm after some advice.


Pulling apart my 05 WR450f to inspect/measure the valve shims.


When the crank was set to Top Dead Centre the timing marks on the Cams were level with the top of the head, but on the inside.


All the research/manuals say to be level with the head but on the outside with the lobes pointing to 10 & 2.


The bike seemed to run fine like this but it seems wrong.


Any ideas??
