One thing to consider with the Blue Thunder heads is that the exhaust port location is raised 5/8" on the standard 429 CJ port.
Headers designed for a 429/460 will bolt on but the raised port may cause fitting issues in your car. For example, a 5/8" raised port in a Superformance with a 460 will cause interference with the steering shaft and may cause the side pipes to hit the top of the cut out in the body.
