Getting the rubber gasket for the front cyl head cover seated correctly can be can be a problem so two things have helped me:
1) I always check/adjust valve clearances on the rear cyl first since it's so easy to get at its cover then do the front cyl, which is backwards from the sequence in the service manual but it doesn't matter. When the front cyl is done, it means the crank is at "FT" so ex rockers are UP. Turn the crank past "FT" so the ex rockers move DOWN and this will provide more room to get the cover in place with knocking the gasket askew.
2) When the front cyl head cover is bolted back down but before all the other parts are reinstalled, I check the front portion of that gasket using a dental mirror and flashlight. It's impossible to see otherwise!
Nick - the cyl head covers are the highest point of the engine so I doubt if an overfilled crankcase would cause an oil leak from the top.
