Durability and longevity wise, are not the stainless shorties far superior to the cast iron logs, which have a tendency to warp, crack, and just plain rot out?

Time will tell... the stock manifolds lasted ten years before I took them off

It's not like adding a supercharger or turbo or hitting the nitrous button.

I assume you put on shorties? As I noted, the increase is even smaller with those. I doubt you would "feel" anything different with shorties. There would be a measurable difference but not much seat of the pants.

Yes and this is an area where money talks. If you are going to go with headers you need to spend some money and get good quality pieces. There are also companies that produce locking fasteners made specifically for headers that reduce the headaches down the road.

While I have never used them myself, I have heard good things about these guys
http://www.stage8.com/
I also really like the look and theory behind their idea.

In the past headers have be notorious with coming lose and leaking. A good set of quality locking fasteners can help to eliminate that issue.

Also, look for a set of headers with a very thick flange. This reduces the odds of heat twisting the flange and again resulting in a leak. Most high quality pieces will have this already.

I have no experience with headers on these trucks. When mine actually fall off I might go that route, I still have a couple or three studs holding the passenger side on lol.

Does anyone here even care what my original post was!?? Like WTF.. I said i have a leak.. Thats the obvious reason im asking about new manifolds or switching to headers.. Guy doesnt even read the ****ing post! I dont give two ****s about wheather or not im getting any gains, or if my truck will be louder, or if your momma cant keep her **** in her *** anymore!.. Thats not my concern. My questions is wheather headers are a better route because they reduce back pressure and allow for more flow which I believe will reduce that change of it warping again to cause a leak! Someone suggested that if I stuck with manifolds instead of header that the OEM headers are the way to go. But my concern is that they crack and warp on everyones truck Including my iwn so why would I want to put the same manifolds back on...???? I believe headers are less likely to have this issue again! Seriously every post i make on here lure in retards and most dont have a clue what their talking about..

You're gonna get tons of great advice with that attitude!

If I were you I would take the manifolds off, not put anything back on, and run it like that! Maximum exhaust flow that way. Good luck bud!

Back pressure has nothing to do with the issue on stock manifolds. It is purely a issue of parts construction and engineering. I am not sure what it is with Ford but they have had a wide variety of manifold issues on many vehicles throughout the years.

If you are looking to avoid the problem then a high quality set of headers might work, however headers are notorious with leaking and coming lose.

I noted some ways to avoid that, if you read my post.

I did see an interesting post a while back with pictures comparing the gasket to the manifold and showing an issue with the last exhaust port not lining up properly with the manifold port. I have no evidence to back that up but the image was compelling and would account for the warping and cracking. The hole was a little smaller then that of the port on the head meaning a build up of heat in that area.

The only things I can tell you for certain are:

I would not use Dorman manifold, stick with OEM. More money but far less word of issues after instal.

Short headers instal with an exact bolt up but without spending big bucks for a high quality set you are asking for trouble sooner then later.

If you go headers you now have to change both, again adding to costs.

A proper instal of an OEM manifold will last at least as long as your current one before any leaks begin so likely long after you sell the truck.

Your attitude sucks and you need a serious adjustment if you want to continue getting help here. There are a few forums I am on that you would be temporarily ejected for such comments and crude name calling.

The term retard is long gone and akin to other no longer acceptable terms that should not be mentioned here.

Good luck with you decision
