Tire sizes on stock rallye wheels.

Okay, so this topic has been discussed a ton. But I have stock rallye wheels on a 72 dart. I was young and dumb when it came to tires and I bought 205/60R14s for this car. Just sits the car way too low. So, can I fit 225/70R14 on the car? They seem to be the right height. But will the front tires rub while turning? Maybe I should do 215/70R14 on front and 225/70 on rear? Can I fit more meat on the rear?
Thanks guys!!
