08 Headers?
Having trouble finding headers for my 08 4x4 v10 F250 Super Durty. I am beginning to wonder if it is because the truck has 3 catalytic converters and the old v10s didn't. I found a set on ebay from a company called jba I've never heard of, and I am paranoid about getting junk headers. I have broken studs and I think the ccs are clogged cause my fuel mileage is down to 10.3 and my performance sux. Any suggestions? Whatever I get I want to out last the motor, so definitely stainless, with ceramic coating, and the thickest flanges possible.

A couple of thoughts... The stock 3-valve manifolds are so free-flowing that a set of headers isn't going to get you anything. Except maybe more noise in the cab 
I think that's the main reason almost no one makes them. There's no real market for them.
In terms of your mileage.... Because the 3-valve manifolds flow so freely, if you have a leaking manifold gasket, it WILL pull in fresh air except when you're really on it. This causes the computer to think you have a lean condition, and it richens the mixture, using more gas. Ever smell rotten eggs when you get out of the truck? That's the catalytic converters working overtime. It'll also make the performance suck.
Other things to look at are cleaning the MAF, fuel filter, that sort of thing.
JBA is actually a well-known header brand, but if it were me, and I had a 3-valve, I wouldn't go there. After all my issues with headers, if the stock manifolds flowed well on a 2-valve, I wouldn't recommend that route for anyone.

I apologize in advance, but all my life I have read stock manifolds = Restriction, Headers = Flow, Performance, Economy, Sound. I have always wondered why they couldn't just design a better manifold from the factory.
I hope you are right, I could save myself 800+ dollars, but I would like to bump this thread for more opinions. I hope you understand this just goes against everything I have ever heard
. Do you perhaps have any further proof, a dyno sheet, flow chart, something? I am not saying you are wrong, I am new to these engines, it just sounds strange

Only headers I have seen for the 3V V10 in the F-series are the short tube headers. They are made to replace the stock exhaust manifolds and connect to the stock y-pipe. Not really much of an improvement over the stock manifolds. The stock 3V manifolds are far superior to the 2V manifolds. The 2V manifolds are horrible.
If there would be a set of long tube headers available that would be a different story. The 3V 4.6l and 5.4l engine have proven there are improvements to be had, however both have far more options available than the 3V V10. If you had thousands to blow you could get a set made but that can be a crap shoot. It helps to be able to R&D header designs on a dyno to make sure you are getting something for the effort.
Banks has a set of headers that could be considered long tubes for the F53 chassis motorhomes. Bad thing is they do not fit the F-series.
If you have not already I would get a tuner from 5 Star with custom tunes. You will notice a difference I assure you, most likely far more than you feel with a set of shorty headers. The V10 is a work truck motor for running the **** out of. Unfortunately the aftermarket is small, even more so for the 3V.

Ok, then I'll just repair the gaskets and studs on my factory manifolds, I just like to upgrade instead of just repair whenever possible, but in this case it sounds like the gains would be marginal, compared to the money I would have to shell out. Thank you BTW.

Well that is something that the headers do in my experience, solve the issues with broken studs. That is one of the reasons I put headers on my 2V at 20k miles.
If I were you I would get in touch with ARP and see if they have stronger exhaust manifold studs available for your truck. If you put the OE studs back in they will just break again.
