Anyone else interested in header flanges? (91-95)

If you would like to get in on this, please post here so we can get a tally going.

Thanks!

p.s. this is for DOHC flanges similar to the pushrod ones...

i would love to get some header flanges but i cant afford it for a little bit.

So how many sets need purchased to get them down to $60 a set like the pushrod ones? I was hoping to start some welding in the next week or two, and if I could have some flanges by then, it would be sweet not to have to dick around with making a set. I would need a couple sets anyways since Ben wants a set of headers, and I would need to be the one to fab them up for his lazy ass, lol. Also if we needed 5 sets made to get the price down, and only me and 2 other people wanted some done, I might be persuaded to get 3 sets, and fab up a 3rd set to sell or something.

Curious as to why you would make header flanges from mild steel. Now would you weld them on first and then heat treat? You would have to. Mild steel collapses under bolt pressure. It wraps instead of going on flat. Lot of leaks, like the cheap sets from J.C Whitney for V-8s. Also won't keep torqued.

Mild steel (1018, 1044, 1144, etc.) is tougher than the stock cast iron manifolds on your car now. Yes, it will deform slightly if you torque the heck out of your bolts but it's still good enough for header flanges. I agree with you that it will warp but all steels try and do that when they're cut except for some of the high end stress relieved stuff. I've got the programs for our CNC's to make the flanges in the next few weeks and I'll probably be using mild steel unless I just happen to have some 4130 or something similar lying around.

Try flat S-7. But I would like to see the program. I run CNC milling. No heat. You have it in Autocad or Smartcam? Not saying it won't work, but I have dealt with too many mild steel header flanges. And the cast manifolds have design built in to keep warpage to a bare minimum. Lot of mass there.

I have the shape in AutoCad 2000 (.dwg or .dxf) and the program is in G code for a Haas mill (or any other Fanuc compatible control). I'll probably still stick with mild steel for the flanges. I've make them before for a Chevy big block without any problems.

mild steel + good header bolts and gaskets = no leaks.

shoot me a PM with how much some good thick big block ones would run me, need to make custom headers for my belair

[RednBlack]

See where your name comes from. I have a Fanuc. Love too see the program if you can E Mail it. Send as a file. I won't take your idea. Not my style. Somebody has to get headers for this motor before I go nutz! I ain't payin a grand.

Anyone seen Aarons headers? I only saw the front side. Kinda looked good. LOOKED GOOD!

[haasguy]

As to the big block flanges, that's been almost 4 years ago and I'm not sure if I still have the programs for that. I'll check though.

As long as you're not looking to sell the flanges, I'll give you the program and Cad file for the flanges. I'm not looking to sell them myself I'm just making a set up for my Fiero and for a well known friend of mine who wishes to remain anonymous right now. Shoot me an e-mail in a couple days (machine is off right now) to remind me and I'll send you the files one night.

Works for me. I got a program for billet dogbone if you want it. No reason to spend $65 if you can do it yourself. Have to buy $2 worth of poly bushings(McMaster/Carr) and have a press. Or if anyone else wants it. It's a Smartcam program..

[haasguy]

You'll get a laugh out of this. We manufacture the dogbones, pulleys, strut kits, etc. for FastFwdPerformance! I have a couple of dogbone programs (and lots of dogbones) lying around already. Thanks for the offer though. I had to build a custom one for my Fiero anyway though. It was kind of a monster due to some wierd angles. I have all their go fast stuff on my car now.

[dykz34]

Ya, you should make some header flanges for less than $100. I'd buy a set!
