You will need to adjust the valves afterwards, but you MUST release the tappets prior to removing, and use rubber bands looped over the intake/exhaust tappets during removal to prevent a bent valve.
The rocker arms (tappets) are attached to the underside of the cover, not part of the head. That is why the procedure differs.
How about the cam chain? Doesn't it go through the head and cam gear or is the cam lower than the head? I'm not familiar with the 500/550 internals.
