I am looking to build my own manifold, but can't find the head flange anywhere. Does anyone have a source?

Mild steel would be preferred, but SS isn't a problem either. Joined or separate doesn't matter.

Like this one ?

I did see that one, but was hoping for a US supplier. The value of the US dollar makes that a very expensive flange!

Do you have a CAD drawing of the flange? A friend of mine can make them on his laser cutter. SS or mild up to 1 inch thick or down to 10 gauge plus or minus .004 on 1/4 steel.

Quality is never cheap and cheap is rarely quality...if the 9 product is not in your budget then make your own using a plasma cutter, drill and hole saw , easy on mild steel .

I don't have a cad drawing, but I can give you a precise drawing with the center to center measurements. Let me know if he could work with that, and what the cost wood be 5/8" mild steel. I would need 4 single port flanges, rather than a joined flange. Let me know if he is willing, and thanks.


I'm not expecting cheap. I am expecting a quality machine cut flange. Even a quality flange is not work an upper $100 price tag. I have purchased many quality flanges in the $75-120 range.

You could pick up a set of cracked headers, and cut the flanges off of them.

I can do center to center hole size and punch it out on SolidWorks. He does not cut 5/8 very often. 3/8 is a common size he cuts and that is still very thick. Are you sure 5/8 is what you need?

I'm guessing but it would probably be about $5-10/ flange for the individual flanges.

It needs to be fairly thick in order to flatten it after welding. 3\8" just isn't enough material to do that. 1/2" would be fine if it's something that is more available for him.

I will draw it and email it when I get off of work. Thanks again.

Nice screen name! I would prefer to start with a solid flat flange, rather than the stamped stock one.

Sounds good. My buddy just upgraded his laser to a Trumph L2530. Nice machine.

I will draw it up and send some prints back to you.

I can also run a test sheet in 1/8 for fit checks. 1/8 is really cheap to cut.

I'm interested in one as well. Thanks.

Two users with a forty six and two name? Lol

I LOVE that song.

Email sent.

Sounds like a plan. I'm not in a big rush. Keep me updated. Let me know the cost of the process. If he needs me to, I will buy a 1/2"or 5/8" plate and have it shipped to you.

I cut my 16v flanges out in SS316 1/2" (12mm) But as we used a 1" thick base plate on to bold them on during welding, we never needed to flatten the flanges!
