76 Scamp Headers?
Hedman SB headers are like $135 from Jegs and Hooker Comps (not super Comps) are around $150.
I have the hedmans on the 360 in my Barracuda. I installed them with the engine so I can't speak for how easy or hard they are to get into the engine compartment with the engine installed but they fit perfect and didn't require any denting or adjusting to clear the engine, suspnsion or frame/body. JUst make sure you use the small head bolts that Hedman provides, a couple of places the bolt is very close to the tubes and the small head allows you to get a wrench on them and tighten them down.
