Big block Fenderwell header & tire clearance

you cant run very tall of a tire with the fenderwell headers, probably worse if you ditch the backspace and move the tire out.
problem is when you turn the wheels hard the tire will rub on the drivers header Bad. think my headmans were slightly better.
think I ran 165r15's and they still rubbed. I think when I put the car back together im moving the engine back in my car ( will have to modify a bunch of stuff ).
