Ding ding!!! This^^^
Love responses from people who have zero idea what they are talking about. It's why I'm such a stickler when it comes to wrong info being posted but it just seems to get perpetuated on this forum so much, it's hard to keep up.....
OP, you need to start over with all new seals and NOT use silicone on a valve cover but instead the proper high temp Honda liquid gasket (or equivalent). Read your service manual for proper instructions on how to properly do it and what to use.
The other thing you need to do is figure out why it was leaking in the first place. Is there a crack in the cover? Did someone else have it off for some reason? Crack in the head? You might be fixing symptoms, not the problem. My thought may be someone tried to do a valve check and screwed up the gasket or lost a seal, it started leaking and they sold the bike. Just a thought, no idea on its history.
And the holes you are talking about are drain holes mostly for moisture, not exactly for leaking oil. If you ride in a pouring rain or soak your bike washing it they should drain away water from shorting out a plug or coil pack. They will drain oil in extreme situations, though.
