I will be getting the kit to make sure but the shop we took it to said the heads were fine. We are going to replace the Coolant temp sensor first and flush the heater core to see what comes out of it considering the guy that did the Radiator said it was very clogged.

yeah a coolant flush wouldn't hurt especially given you were told it was very clogged. there may be some debris in the system causing a clog that is not allowing fluid to pass freely about the system. for 100 bucks it's not a bad place to start....and at least then you'll know you have new fluid in the system.
