Default Pic Request - Headers

I searched through the archives (and some other sites) for pics of the Hedman Headers Part # 61448. I haven't had any luck.

These are the elite headers for 84-86. They have air tubes but no egr provision and should be ceremic coated.

Can someone show me what they look like?

Thanks in advance.

The Hedman website doesn't have a pic and neither JEG's or Summit Racing has pics either.

These sell for $470 at both places and that leads me to a question. Why did you select the Hedman Elites compared to the Hooker Super Comps? The Hookers are more money and both are ceramic coated but one big difference I noticed is that the Hooker's are "tuned" and the Hedmans are not.

To me, "tuned" headers has meant that the tubes are equal length and that the bends are smoother and no crimps anywhere.

The Hedman's are also thicker material (14ga) as opposed to the Hooker 18ga. That makes the Hedmans heavier. The Hedman tubes are slightly longer and they are called full-length as opposed to the Hookers as being "mid-length".

Would there be a difference in where the power band is between thw two headers or is there something else?

Send me your email and I will send you some pics of my Hedman Elites I have on my 85. Keep in mind that I have removed the AIR tubing. Also keep in mind that these headers go up into place in about 30 seconds with no engine mount clearance issues the Hookers have.

I have Hedman ceramic coated headers that I haven't installed yet. I think they are the elites, but I'm not positive. They're in my closet at home and I can take a pic Wednesday if no one else gets one sooner. Mine have no AIR tubing.

How did you deal with the A/C rear mounting bracket?? Is it just a matter of bending it to get the holes to line up?

The tubular bracket on the rear neede no modification at all. I used the original stud in that position. The engine is out right now and for the life of me I can't remember if the stud was all I used but I do know I did no modification to the bracket.

Which is where my problem is, I'd like to see what the air tubes on the 61448's look like.

I don't think I could get into that without causing a war I'll just say the research I did, and the reasons I want headers, led me to choose these particular ones over everything else.

I sent you a PM. I mostly want to see what the air tubing looks like, but I can post your pictures anyway for reference...

The standard version has 1/4" flanges, the elites have 3/8" flanges. That's the easiest way to tell. Also the elits use 14gauge pipes, while the standard uses 18gauge pipes (in line with Hooker's specs).

Somebody out there has had to have used these... I guess keeping the smog stuff while installing headers probably isn't the most popular of choices.

EDIT:::I was wrong- the standard version uses 16gauge tubing.

I sent my pics but they will do you no good, I have removed the AIR tubing off them. The Elite series can be identified by the small metal tag on the front tube drivers side header. One of the pics I sent has this shown.

Thanks! I'll post one of them tonight for other members to see. Hopefully I'll get a emmissions equipped pic to compare them to in this thread.

Also... I have the standard headers (68440) and they have that tag too though... and the ones I have are definitely not elites (1/4" flanges). I am pretty sure hedman puts that tag on all of their headers (also the part number is stamped on the flange of my headers).

Be sure to check the port size. The Elites I got had smaller ports than the head.

So the non-smog ones come with air tube holes in the top of each primary? And can you even get to the #1 plug? I think Agent86 has them, try him. Also, I'm pretty sure the Hookers aren't equal length. Nor does equal length mean much on an unbalanced 350 firing order. In fact, unequal lengths could be designed to be more beneficial.

So... Agent86... pics?

My reason for wanting to see what the smog hookups look like, is to see if I want to get them or not. It might sound dumb, but if they look like the factory ones I'd rather get them. If they look like the generic fitting in the summit picture of the standard set with smog provisions, I'll just get jet-hot to coat the standard set I have and use them instead.

Your original AIR tubes are made so the "backfire valve" is facing forward. The Hedmans are made so the valve is pointing up, I had to use elbows to get them pointing the correct direction which also made the connection point higher up. Since I did the mods I have and the way the hoses cluttered everything up is why I have removed the AIR system.

So the smog tubes look the same as they do on the standard version... That looks pretty bad. That answers my question though- I don't really care for that setup... I guess I'll go with the non-smogged set. Now I just need to figure out whether to get my standard set coated, or buy a new non-smog elite set coated... decisions.

Thanks for everyone's input.

Since smog equipment is not an issue for you then I strongly recommend going with the non-smog header. I sure wish I had, if I had I wouldn't have 8 brass plugs sticking out of the tubes. As you can tell by the pics, the coating is dulled, this is due to a lean condition I encountered when the headers were new. I plan on using this set at least this next year then another set of non-smog tubes will be in order.

If you decide to get the Elites, please post the port sizes of the headers and heads. Thanks.

We purchased the uncoated ones and had the primaries matched to the alum head port and welded in a bung for an o2. We also had them coated inside and out. Coating them inside helps the scavenge effect from what I understand. They were not too bad to put on either. Good luck to you if I can get some pics I will post them.
