Which heads?

So I bought that tire hoping to compensate for the 4.30 gear, was that a bad move? I will contact them and see what they can do with the stock convertor if I do have a 67 trans.
That tire and 4:30’s? I’d be OK with that. I’m doing that now but with 4.88’s in my Duster.
MY Cuda has 4.10’s and 255/60/15’s.
It’s all in the same ball park-ish area.
