I have Hedman 66001 on my 454. They have 2" primaries with a 3" collector. The ground clearance is good and I have very good access to my spark plugs and header bolts, however the clearance around my AGR Power Steering gearbox was very poor. It basically didn't fit. I had to ding the driver's side headers in 3 separate places to work around the box itself and the pitman arm. That was very frustrating. I also wrapped 2 of the primaries in a heat wrap to protect the steering box due to how close they run to the box. So there are some pro's and con's about these headers, especially if you have a power steering gearbox. There are pics of these headers on my website.
