Hey Dennis... im going thru the same thing... the Trick Flow heads have to be wider... i have only 3 1/4 from the head to the inner fender on the passenger side... the Dougs header measures 4 1/8 wide at the flange to the outside of the bend. I measured my engine centerline from the crank to the frame and it spot on. Im at a standstill with this i cant return them because they have been “massaged” so im thinking of cutting them and making them the width that i need...
