Hi everyone,
   I have been a long time lurker on this site and really appreciate all the great work you all have been doing to share your knowledge.  It is super helpful for an amateur like me who likes to fiddle with espresso machines.    I have a La San Marco 85-16m-2 that I have had for a couple years and recently both heads started to leak out of these bolts on the top of the head.  I tightened them down and they stopped leaking.  Anyone know what they do?  I assume the vibrations caused them both the loosen up, but I am curious why they are there.  

You can see some pictures here.

Thanks
Zach

Also, any chance anyone has a manual they can share with me?  I can't seem to find one online.

Just plugs. They just seal off the holes made when the grouphead is machined.  You might want to put a little teflon tape on the threads.
