Dougs or TTI Headers?

How about adding a third header to the poll? Heddman 75109/75110. I got a set of Harold's headers but am reconsidering as I'm now planning on a stroker and need the breathing room. Heddman's look to fit the bill with 1 &3/4 or 1&7/8" primaries and a 3" collector versus the 2&1/2" collector on Doug's. Anyone use the Heddman's? Tire clearance? How much of a hack job on the inner fender's as compared to Doug's and Hooker's?
