Compression Test Blues

[TooManyAudis at aol.com]

I did a compression test on my 95 A6q last night. Looks like I bent at  least 
2 valves, as two of the cylinders registered 0 PSI. The others were 168,  
170, 150 and 110. 

So, it looks like I'll be r and r'ing the heads. More  work than I wanted to 
do, but that's life at times.

Is there a post  covering this procedure. I'm flying a bit blind due to a 
computer hard drive  that died, leaving me Bentley-less for a while.

Right now, I'm most  interested in how the EM's disconnect. Do I do this at 
the head for easiest  removal or at the downpipe, then disconnect the EM from 
the head when it's off  the car.

Also, my current headbolts seem to be of a unique configuration,  in that the 
male end is on the bolt head, whereas the replacement bolt heads  will have a 
female end. Seems like a Torx or polydrive head on the current  bolts. 
Anybody familiar with this, and what's the tool needed to remove. A  12-point 11mm 
socket will fit snugly on the headbolt. Is it worth trying to use  this to 
remove the bolts, or will I risk rounding the bastards off?
