I've got a '67 327 sb that I'm trying to pick headers for. A trusted source has suggested a collector size, tube size, flange size, and coating. The only dilemma I have now is shopping online I don't know whether to pick headers according to the body of my '67 c20, or according to the '96 Vortec heads on the engine. I don't want to buy headers that fit the body style but don't bolt up, or vice versa. Thanks guys!
