I have the header problem also. I went with a set of fbody headers off eBay and made some modifications to them and my frame just to find the drivers side hits my lower A arm. I don't want to lop off a chunk of my A arm to clear and i don't think I can modify the header to make it work. I don't recommend fbody headers for a 66 this may also depend on distance from firewall and if you raised the engine.
