A/M Headers flange
 

I'm looking at this set of used ceramic coated Hedman headers for cheap. They have the p/s box dent in them and another dent at #2 cyl, but otherwise are real nice.
My question is, has anyone seen the round collector flange? I'm used to seeing the triangle 3 bolt one that bolts to my exhaust.
I figured for $100 you can't go wrong, but if the flange is that different I don't know if they'd work. They're 1 1/2 hr drive so I won't know until I actually see them.

Any ideas? Thanks!

Dave -- I wouldn't think tet round collector would pose a problem. The collector is probably 3 or 3.5 inches and three or four bolts. The sealing surface must is still inside the collector mounting bolt holes. TAZ

So as long as I can pull the two sides together on a header gasket I should be good to go. That makes sense. So you think $100 is worth it? Seems like it. Dents are pretty easy to get out.

The only issue I see here is after scanning through various Hedman Headers I do not see any with this style of collector. Ask whoever has these for sale to give you the Hedman part number -- sometimes stamped into the flange.

I picked them up last night. They're Hedmans # 65001. That means they're 2&quot; primaries which is really too big for my motor, but I don't think it'll make that much of a difference on a street motor though. It should just move the torque up higher into the RPMS. Hedman says they're good for 396 up regardless of HP/Tq. It looks like someone might have welded a turbo flange on it for the collector flange or something. The 65001 come uncoated, so someone had these done after they were bought. I might convert them to the standard 3 bolt style or just fix the dent and flip them. We'll see. Except for the dent, they're in excellent condition.

OK -- that explains the flange issue ... they look pretty good. TAZ

I'd get some lead pack gaskets and make a 4 bolt flange for the exhaust.

I decided that's the route I'll take. If it is a turbo flange like I think it is, gaskets should be pretty easy to source.
I just matched up the headers to my set up. I don't know why they're dented where they are. Its no where near the PS box. Might have hit something or clearanced them them for a custom rack and pinion maybe.

You could also use a ball flange, requires no gasket.

Would that bolt up to the header flange on mine or would you need to weld a new flange on?

edit: Looking at the price of a flange and two turbo gaskets, I might just convert it back to a 3 bolt. I'm seeing $22/gasket and $28 for a flange. Uh, no....

I think something like this welded on the exhaust will work if I can find something with the same bolt spread.
