I had a bad night. Found out whoever I bought this 94 civic from snapped one of the valve cover bolts off into the rocker post, drilled it crooked, and gave up. I drilled it, fought with it, somehow trying to tap an easy out in there I snapped the whole side of it off. What more could go wrong, it took about another hour trying to get the rest of the bolt out of there. Anyway does anyone know where I can get a new post in which the valve cover screw goes in? I has a 3 on it. I wanted to share my experience with ya...

 

If I recall, the parts the bolts go into are also cam caps.
As such, you will have to get a new cam cap and take the head to a machine shop so they can line hone the cap to match your head and camshaft.
