I want to put some new headers in my 86 f250 460 7.5 I've been looking and doing some research. Want to see if anyone wanted to add the two cents in or what not thanks
I know it's tempting and looks "hot rodded", gives a little better sound, and supposed to give more power(but it's hard to notice) but I would think about it a little bit before getting some headers. Have you ever worked on a vehicle with aftermarket headers? If you have, then you will be reminded of;
How hard the sparkplugs are to get out.
How the starter won't come out.
How the heat duct for the aircleaner won't work anymore.
How the exhaust hangs really low after the install, and gets in the way of tranny service.

I've never done a dyno back to back with a 460 like on my truck, but the power gains on my 78 vette and most of the modern Corvette setups I've seen have been quite immense.
The spark plugs are on top of the tubes on a 460, so I don't see how headers are going to get in the way there.
The air cleaner heat duct, some kits include kits so you can adapt that.
I've not dealt with the starter on a 460, but my experience with headers has not been bad at all.
It is suggested to put a late model PMGR starter on a 460 with a header install. Smaller and higher tourque, also not as affected by the heat as a shoe type starter. It will fit just find and requires very little modification to the starter circuit as it has a starter mounted solenoid. And whatver you do, do not wrap the headers.

Im not sure how a 460 is setup, but I don't have any of these issues with the hedman headers on my 302 EFI...well...other than the exhaust being a little low, but I fixed that with custom bent exhaust to go back up over the tranny crossmember. My spark plugs aren't hard to get out, and neither is the starter. However, on my 70 chevelle I did have problems getting the starter out with headers.
Header wraps traps water/moisture etc and causes them to rot. read the warranty from most header manufacturers and they specifically tell you that wrapping them will void the warranty.

True, and if you have a leak that gets on the headers, they can start a pretty serious engine fire.
