Hello, I have a 66 nova 2 door hardtop. I am gonna install fenderwell headers on it. My question is do i have to run front runner tires or not? I have 14X6 wheels on fron now and not sure if they will clear headers. If anyone could help i would greatly apprecitae it. If i do have to run a frontrunner can someone give me a tire size please that they run with them and have clearance. Thank you all in advance for the help. Daniel
