Roofus, I changed out my headers (the ones from OKc got them from the same place) went with 67 camaro nova headers, they fit better I did have to slightly relieve the frame on the passenger side at the rear of the engine. they really look good and they have the thick flanges. I own a tbi 350 also and the first 2 things one does to these engines is to improve air flow in, and air flow out....Kieth
http://kieth.smugmug.com/Trucks/66-GMC/13311086_gRF57#1135655008_TmRkaI have a 350 hp. fuel injected 350. I was wondering if a universal set or a camaro, nova set would fit. On craigslist there are used ceramic coated good headers fairly cheap. thanks
