questions about a '92 100

[JordanVw at aol.com]

i am contemplating on buying a '92 Audi 100 w/ 2.8V6.   the car has 175k mi.  
 the top end was done 25k mi ago.  but recently the car has had rough idle, 
lack of power, and the temp gauge wasnt reading warm, and there would be no 
heat coming from the heater blower motor.

a compression check resulted in the following:

drivers side:
135
125
120
passengers side:
10
10
10

does this sound like a blown headgasket?   seems odd that the top end job 
doesnt have 25k mi on it for the headgaskets to blow again..   or are these early 
2.8 V6 engine pretty well done at 175k mi??   any ideas?  or should i not 
open this can of worms.??

thanks
