Are you talking heads (the block of iron that holds the valves), or headers (big tubular exhaust manifolds). If you're looking for factory 4bbl heads good luck, if your looking for headers check out the online store, www.summitracing.com, www.jegs.com

The only headers so far that we early Bronco guys have found for a Cleveland in the 66-77 are the Sanderson FC3s. They are for a 4V head, so you should be in business there. They make a copper gasket to use those headers on 2V heads. I'm going to have a guy here at work waterjet me some 1/8" flanges to adapt them to 2Vs. Sanderson sells them in bare metal and coated:

I've already got a set of 4v headers for a 71-73 stang that i can salvage the flanges and make my own zoomies if I have to, but I wanted to know what my other options were first. I was wanting aussie heads for a 400 I might be putting together and want some more compression. Recently my dad decided he wanted to start mud racing at Osceola, I have an 80's bronco found for him and was thinking of putting together a 351w for it using parts I have collected, but that will rob two other projects of engine parts. So the new trailriding rig could get a nice torquey 400 and the 67 bronco mud racer will get regeared with 4.56's and a 4v cleveland I can get for $400.

Are you using US or Aussie heads? From what I understand, the US 2V head has less meat around the exhaust port, and there can be exhaust leak problems. The Aussies are supposed to have a larger mounting surface. I don't know myself about the 2V head to 4V headers, but I do know that 4V heads to 2V headers will leak like hell. I tried that once.
