Headers for a inline 6 ??
Can you get headers for a inline 6 I have an 84 f250 and can't get the intake/exhaust off to clean and re do the gaskets. Considering putting on headers if anyone knows of some. But how can I do that with the intake? Since they mount to the exhaust and it has the egr tube. Any info is great!

There are a good number of headers made to fit these engines. There's even the 87-96 EFI models that used 2 separate 3-1 manifolds, like a V6 would have.
Most people do the manifold to header (or EFI manifolds) swap in conjunction with an intake swap, so the EGR tube isn't an issue.
The factory intake and exhaust manifolds are separate units, but they bolt together under the carb.

Save yourself some grief and use the EFI exhaust manifolds rather than the headers. On an otherwise stock or mildly modified 300 the headers are expensive bragging rights. The EFI manifolds are not prone to loosening, breaking, fitment problems, etc., and there is not enough performance difference between the two to make a difference.

I disagree about the performance difference. The long tube headers will always perform better then the efi manifolds. But I do agree that on a stock or mild 300 the EFI ex. manifolds are a better choice. But they do have there issues too. I've seen plenty of cracked EFI ex. manifolds.
Now you can either go to a salvage yard and pull a pair out of a 87-96 Ford truck or van with a 4.9L. Or you can search ebay and find a pair.

I thought I had pretty much covered what the EFI manifolds were........

Another vote here for the EFI manifolds. Hard to beat their durability and sealing characteristics. I found a little casting flash that needed smoothing out, matched the ports to the gaskets. The ball and socket connections (manifold to head pipe) requires no gaskets, and is a good seal. Any headers I've had with the 3-bolt flange gasket has proved to need regular tightening and/or gasket replacement. Starter motor access may be a concern as well with headers. EFI manifolds I've seen also have threaded hole for EGR tube.

Ok so if I wanted to replace my stock intake exhaust bolted together manifold with the efi manifold. Would I still be able to use my 1 barrel carb? It's an 1984 f250. I just don't want to order install and have nothing work. Waste time and money!

You can re use the stock set up. You will need toput a new starter in when you put the headers on, it is impossable to replace the starter with the headers in place.
you also have to relocate the brake line. I would go with the efi manifolds for your app, it would be pointless to put headers on a stock set up.

With headers or the EFI manifolds the feature of the stock manifold set-up for heating the intake will be removed. With a Clifford or Offy 4v manifolds this is no problem as water heat can be used. I'm not sure what can be done to heat the stock intake. Without the heat there might be driveability issues due to gas dropping out of suspension and puddling in the bottom of the intake...loss of atomization.
