I never heard that. Sounds weird. I have Clifford headers and an Offy intake on a 292. They are the long tube headers. I've seen the Hedmans and they look like a clone of the early ''Clifford Research'' headers like mine.
I have heard some kids with lowered pickups with a 250 complain that their long tube headers scrape on the pavement, but then I can't see what they think they're doing in a truck anyway. JMHO.
They are the same headers for 250 and 292, but the heavy duty tall deck 292 is about 1 -3/4" taller than the 250. Shouldn't be any clearance problems with a stock stance truck w/250, especially not in a 3/4 ton. They do make a shorter header too, but the long tubes are great for torque.

Unless it's a fitment issue with the water-jacketed Clifford intake [which can't be notched or grindered much without getting into the water jacket] where the exhaust and the intake manifolds mate with the head. IDK.

Maybe someone else knows more about the L6 Hedmans. I have Hedman 'hedders' on a 350 V8 in my '71 GMC. I ceramic coated them. They run good on my Jimmy.
