RW> My 55 Chevy had a 30-30 Duntov cam in it. Adjusting the valves (.03   
   RW> intake and .03 exhaust} with the engine running and the covers off   
   RW> allowed the oil to pump over the fenders. I found a set of rocker    
   RW> clips (still have them today) that covered the oil hole in the    
   RW> rocker which kept the oil in the engine, until it flooded the head    
   RW> and overflowed onto the exhaust. I learned to do only one bank at a    
   RW> time, shut it down, clean it up and re-install that cover before    
   RW> tackling the other bank of cyl.   
      
    MH> I have never done anything like that, nor would be brave enough to   
    MH> work on the open engine while it was running.   
      
   really?? this was the normal SOP "back in the day"... you made the rough   
   adjustments to the valves and then fired it up so as to place the feeler   
   guages in the slots while the engine was running to ensure that the gap was   
   proper while running... the only real "gotcha" was watching out for the oil   
   pumping up out of the push rods... it could get real messy at times ;)
