I've got my new 460 built for my 1997 F250 4X4 CCSB I'm going to try to get it installed before my surgery on the 17th. I purchased the Hedman Headers for my specific application and am looking for tips. Such as; the headers should be quite a bit hotter than the stock manifolds, I'm looking to wrap them and already have fiberglass protective boots for my plug wires, any other problems youve encountered? Fitment, how well did they bolt in and are there any modifications, bends, or alterations that i need to do ahead of time? Emmisions, "yeah I know I've got a battle ahead of me" I have the bungs pre welded in to install the O2 sensors and will most likely need a new Magnaflow cat because mine is currently filled with oil from my current grenaded engine, but have any of you passed emmisions with the headers installed and if so how? The engine I built is basically a completely rebuilt 1996 460 with new heads and a RV cam with "I can't remember the size" but the next size up injectors that are still relitivly small, the throttle body is stock with a little polishing on the inside and the intake has the internal horns removed. Any help would be appreciated!
