Headers for 60-62 C-10 w/ torsion bar frontend

[runningiron]

Need an idea what brand and part# of SBC headers in a 60 Apache with a standard trans. I will be installing a 350 with a cast iron Saginaw car 4 speed into my 60 1/2 ton Apache. I will be removing the stock rear engine/trans crossmember and using the side engine motor mounts in front with and an automatic crossmember to support the tranny in the rear. I will be using a cast iron bell housing with the passenger side clutch arm assisted by a slave cylinder out of a 1960 C-40 truck that came with a 283 . Any ideas would be greatly appreciated. Thanks
