Default B6 a4 3.0 no start... weird compression readings...

Hey guys, I'm having some problems with this A4 I just purchased. I bought it not running. It cranks, almost fires but it doesn't quite get there. It has spark, and fuel. Starting fluid does nothing. I did a compression test and here are my results.

Drivers side head:
180
180
180

Passenger side head:
122
121
123

I heard the compression is supposed to be at 150PSI. Why the heck is it at 180? I don't have any timing codes. Anyone know what might cause the no start? Or the high compression?

Also, this is the 3.0L V6.

Probably cam timing off on the head with low compression.
