Go buy you an LA exhaust gasket and see how it sits on the ports and bolt pattern. I think an LA header will work on the econo pattern.

Cab, I called TTI and spoke to one of their techs, not sure who it was. I asked him about using the w2 race headers and possibly filling in the inner bolt holes with weld and drilling new ones, he said the holes would end up inside the primary tube.
I also asked about shipping me a set with flange just tacked on so I could cut them off, dent the center tubes and weld my own Econo spacing flange on. He said he didn't recommend doing that and basically said it would come out terrible looking due to the amount of dent needed to fit them in a econo flange. Basically the only option the tech gave me is adapter plates. I don't have the heads with me here (at the machine shop) but they have been worked a bit . Without looking at them myself though, the TTI tech gave me the impression that the bolt spacing is such that it would pretty much be impossible to use any decent size tube on them.
I'd really rather not use adapter plates. Kind of a PITA to install/take off, another point of potential leak, great possibility of potential fitment issues with spacing the tubes out and possible flow issues. Just seems like a lot of downsides and not the 'right' way to do it.
I am really considering just asking TTI again to ship me the headers with the flange just tacked on. I am sure I can work something up with either step ups or dented primary tubes on the center ports. Only issue is at that point, doing that much custom work, I feel like I should just use my hooker super comps as a template to weld up my own out of T304 stainless. I was really hoping to just buy something off the shelf and be done.
I am going to contact tubular automotive and see what they say, thanks for the link Duster!

I have Tubular automotive headers on my Dart. I dont think they make headers for an E body but call and find out. I have two sets of plates one for standard heads and the ones on the car for W2 heads I have them on my Indy 360-1 heads. If you want to borrow the standard head plates for fitment Let me know they are just sitting in a box. One thing about Tubulars mobody else has gaskets that fit their headers you have to get them from them. My headers are old and worn out I am debating between another set of Tubulars or TTIs.

Just use adapter plates. It ain't that hard. You can make them yourself with some 3/8 aluminum plate, a gasket and a countersink.
Bolt the to the head with a THIN coat of orange silicon and be done with it.
Thousands of engines have been used with adapter plates.

Thanks Ucudant! I just saw your PM, thanks a lot for those pics!
Wow, looking at the W2's overlap, they really don't leave a lot of room there for anything bigger than 1 5/8ths.
I am still on the fence about what to do. If I run a 1 7/8ths LA or W2 Race header with adapter plates for the econo, there is a good chance I will have to modify them to clear the power steering box, which means I will have to buy them uncoated and then have them coated (unless a small dent would be enough). That is going to be a major PITA with shipping/coating costs and all.
On the other hand, if I modify a set of 1 7/8ths TTI W2 or LA headers to use a W2 econo flange, I'll run into the same issue of having to send them out for coating.
What I'd REALLY like is a set of stainless 1 7/8ths headers for an LA or W2 race headed E body. This way if I need to modify them either for the P/S box while using adapter plates or for the flange to put my own econo flanges on them, I won't have to worry about any recoating. Just weld and be done with it.
Anybody know if any companies that make stainless headers for these cars?

Only places I know of are very big money. Headers are a PITA.
I've made 2 sets. After the first set I said NEVER AGAIN.
Yep, I'm a slow learner.

You're welcome This set isn't pretty and requires the adapter plates I showed in an earlier post but I think they're supposed to be for an A body. My buddy has them now but has no plans to use them..... I'm unsure of the size but can check if you might be interested. FYI I'm sor t of interested in finding a dual plane W2 intake TTi makes a 1-5/8" to 1-3/4" W2 step header that fits PS http://ttiexhaust.com/Category-ClassicHeaders/340W2/TTi340W2.htm

I make headers all the time(thats part of what I did at Chrysler)... these are 1 7/8" econo W-2 headers I made for my Rampage... I did the flanges also... this is 3.5" collectors EDIT the flanges started out as 1 piece, that makes it easier to set it up and for welding then I cut them down to what you see.. they are also 3/8 thick so no worping

On those headers I built I had to bevel the surface of flange to clear the plug socket.. but that is with 3/8" flanges... with the LA gasket did you end up with the hole that are close to the port.. I always use the holes that are out farther so port work doesnt get into the holes that I mount with.. I am just into the close holes with porting

I had a header gasket with the multiple bolt pattern holes and I matched up the holes with my LA hooker super comps and marked them.
The holes lined up exactly with my W2 heads. I wasn't aware that they made W2 heads with an LA bolt pattern? I guess I'll just be going with a set of TTI 1 7/8ths LA headers then, unless there is something I am missing here like spark plug clearance? It looked to me like with the angle plugs I shouldn't have any issues with clearing the tubes.
Yes thats the standard LA pattern, I was using the common holes to align the gaskets in my photo's....thats what I was showing you. The plugs clear the tubes. Mr P body stated when using the wider center tube mounting pattern and a thicker flange it will interfere with the spark plug socket, I run a narrower bodied spark plug on mine so I use a narrower socketand it fits.
