Your info does not expressly apply to his situation, since he was retiming a WR cam to YZ timing.
If you take a look at my thread re timing my 01 YZ426, you'll see some nice hi res pics. Compare my cams and yours; you can see that my punch marks on the exhaust cam are in a different place to yours (and if your exhaust cam was marked up with where my punch mark your engine would be timed like mine is.. i.e. YZ timing)

He can use my pics and his pics to compare the difference of where the punch mark is and check that, if his machine contained a proper YZ cam, it would be timed up as per a YZ, no? Or thought about it another way, if he uses my pics to put a dot of white correction fluid on his cam where the indent is on a YZ, and then times to the white dot he'll arrive at the conclusion that the exhaust cam in the WR is on YZ time.
I thought he was looking for a double check that he hadnt timed up by moving the WR exhaust sprocket one tooth in the wrong (anti-clockwise) direction.. But if this post has helped clear up any confusion, then thumbs up!

I don't think so. The timing mark alignment on either engine is identical in stock, original form, regardless of whether it's a WR or a YZ. The only difference is in the position that the OEM WR camshaft is installed into the sprocket.
I think you misunderstood the intention my post..
In his case, in which he was resetting a WR cam to YZ timing specs, the intake marks are used as intended, but the exhaust cam is re-indexed one tooth retarded from its original marked position. Thus, the pictures of your correctly aligned timing marks don't really address his particular situation.

if you want, you can spray some cleaner down the hole (with the plug in only though) and the oil will run out the side hole.
ALWAYS blow compressed air into that hole before removing the plug but make sure you have the spark plug wire removed first.
