My experience with FE headers on my GT 500KR is the Hooker Super Comps. Only issue I had was the collector flanges with interference at the transmission mount cross bracing on the floor pans. Collectors should have been 1/2" to 1" longer.
Installation was made easier by lifting the engine 3" to 4" and leave off the block engine mounts for header installation. I installed the headers through the radiator support and was able to slide them up along the side without any issues. (Did grind the shock tower reinforcing about 3/16" for header bolt clearance. Using Summit small diameter stainless steel header bolts.) My car is using a Genesis block side-oiler with 482 cu. in. built by Keith Kraft. Now that the installation is done, I wish I would have used the Hooker race headers without flanges for my application, as they are larger diameter tubes and would not have had the interference issues at the transmission mount bracing.
Hope this is of some help to anyone installing FE headers. I probably have a series of pics of the install.
