Looking for large tube SB headers

alright, called up hedman husler AGAIN...yes one tube per side runs over the frame rail...7 and 8 , but the tech on the phone tells me minor, if ANY inner fender modicications will be needed....we're not talking hole saw and run a tube into the wheel well. MINOR/NONE is what the inner fender modifications was explained to me as. on my dart there is some room between the frame rail, and the unibody of the car...that must be where most of the 7/8 tube squeeze....not a fan of a remote oil filter kit...but not horrible i suppose.
