1971 Chev 1/2 T 4wd with 454-exhaust manifolds?

[Monte Jack Hanks]

Hello, I am looking for any suggestions re exhaust manifold or headers to fit this application. I've had Hooker Super Comps on before, but they are pricey. I think I've found some Hedmans that will work. However, I would prefer to use stock manifolds. Found some on a 402 in a '71 GMC that should work, but my engine sits lower so they won't clear the frame or the clutch linkage. Any ideas out there? thanks, Monte
