Timing 400ex

I recently purchased a 2003 400ex that needed some "minor" work.
It was blowing oil out around the spark plug/valve cover head area.

Well long story short there was a tap broke off in one of the valve cover bolts and when I took the head and cam/timing chain off I never marked anything (like a idiot)

Now when I go to re assemble this thing how do I get it back in properly?

Appreciate the help.
This thing has been an absolute nightmare for me. I just wanted to ride 😔
