Hooker super comps STOCK SUSPENSION

I had to disconnect my centerlink and run it through a space between the pipes on the driver side header on my 68 Barracuda. The instructions from Hooker mentioned that this may be required on certain models. It also mentions some cars will require raising the engine 3nches to install headers. I installed Hooker Competition headers PN#5901 on my car, not sure if Super Competition headers has a whole different set of issues when installing. If some company could design headers so that nothing needs to be removed modified or altered in anyway, so that one could just slide the header straight in and have no clearance issues with power steering gears or any other component on the car they would make a killing. Everyone that owns a muscle car would buy their headers only and no else's.
