Blown Head Gasket or Cracked Block

Checked the vacuum lines this morning and also did a compression check. This is a 74 225 motor so I used that to refer. what the book says that each cylinder should be. Each cylinder was within 2 lbs of each other. The compression was in and around 120lbs on each one. This has not changed from when I tested it when we got the car.
Would a bad condensor cause this kind of idle issue?

Thank you
Rick
