My standard pressed red motor covers have 6 each
2 on inlet side
2 on exhaust side
1 each end
Leaked like a sieve until I used about a full tube of ultra blue to stick them down.
Enlarge the pic in this ebay ad. You'll be able to see the 6 holes.

But its not uncommon to put extras in but not usually on sheetmetal ones
One front and one rear
You can see them here

I use rubber gaskets too and I appear to get less leaks, the rubber are quite expensive but then again in my case do not require a tube of sealant and are reusable.

Bocam recommends using cork not rubber with their sheetmetal ones

On my Kingswood 202 rocker cover I put 3 beads of the black silastic let it dry, another 2 on top of that.
When it was all set, I used a razor blade and trimmed it all flush with the bottom of the side lip.
Red loctite on the bolts and don't over tighten- never leaked again.
Oil filler cap, breather grommets, front and rear seals, side plates and dizzy hole still leaked like a sieve but the rocker cover was fine...
