Heater Or No Heater,thats The Question

We are getting close to the engine swap from the / to the 360 and we havent decided whether or not to keep the heater or by-pass the hoses and get rid of the heater all together.We live in So CAl so you really dont need a heater other to defrost the windows occaisionally.the way it works now you have to wipe it with a hand towell to defrost it and then it blows very little hot air up to keep it clear. What are the pros and cons on removing it.
All opinions are welcome

thanks---Bob and Bryce
