They look very nice. I have stock 340 manifolds and with a 4 speed it sure seems tight just getting a single collector to the manifold with the steering box, clutch linkage and torsion bar in such close proximity. I am always amazed when I see folks get headers installed, especially on BB cars. I actually installed a mini starter in mine which made me feeler better about gaining more clearance space and being able to pull the starter without yanking other things out. Are you going to run a min starter?
