My car has a dyno tune done on it but I have changed a few things on it like cam and heads and it is running rich. I was wondering would it hurt my engine if I drive it sometimes

 

You need a tune .period. Why would you spend all that money on heads and cam and not use it properly? Yes you can hurt the engine and your drivability is suffering as is ,tune it .

First!

 

How did you determine it is running rich?

 

Probably the usual rich condition crap... gurgling/popping on deceleration, potent smell of gas, poor mileage, blah blah blah

 

You could wash the rings very easy. Plus oil and gas do not like each other.

 

As long as you don't do quick rpm changes the computer will use the MAF and O2's to recalibrate your fueling. You shouldn't worry too much.... it doesn't take very far from 14.7 to get bad fuel mileage. just use WOT when necessary...
