Spitfire Headers,Delivery!!

How do these compare to the Schumachers in performance and fit for a big block in an A-body(68 Barracuda)??

Thanks
Derrick
Wish I could answer that for ya but can,t.I do know that these will fit early a-bodies pre-67.My 66 Dart now has the 360,manual steering,floor shifter with cable.I have to weld on extensions to clear torsion bars.I think Harold ships them as shorty,s so you can modify for 4 speed(around z-bar or auto linkages?)it,s tight in there.
