440-1 header flange

Im in the process of starting the mock up of my boosted low deck big block swap in my valiant and im trying to source out a set a 1/2 thick header flanges for a set of 440-1 heads does anyone have a cad drawing of the header flanges or a basic drawing of set of flanges for these heads i could have turned into a cad drawing. Any and all help is always appreciated
Thanks Aaron

Headman makes nice flanges with stubs

Thanks but stubs arent going to work for me i need all the room i can get also i have a shop thats willing to cut some 1/2 thick flanges for $90 i just need a pattern or template
Aaron

How about using a header gasket as your template?

Yes thats a option ive thought about but i was hoping another memeber may already have the dimension and would be willing to share.
Aaron

very nice stuff here.

Hope to get my headers made very soon for the new car

Pittsburghracer whats the thickness of those flanges and if you dont mind me asking what was the damage to your pocket book.

I looked around for 1/2" flanges and most wont make them.. and the
ones that would wanted about $200.. you would be better off measuring
a gasket and having them cut at that shop.. also.. make them out
of stainless... I ended up making most of my flanges

They are 3/8 thick and I will check when I get in the house but think they were around 200 dollars shipped

Ok cool thanks for the advice guys i might just have to order a gasket and take it in to the shop and have them use it for a template
Aaron

Make sure the gasket lines up well with your heads... it shouldnt
take the shop long to set up a CNC program to cut the flanges based
on the gasket... but it will add a few bucks to the cost

I just ordered a set of gaskets from tti

Schoenfeld has flanges. I think they even provide dimensions on their website.

Check the website for Flatout Gaskets. They used to have drawings with dimensions of all of the gaskets they made.

Cab, I tried to send you a pm and your mail box is full?

Sorry for the hijack..

Thx. Mike

Thanks AndyF i think found what i needed the funny thing is i have there website bookmarked on my phone and was looking on there site earlier in the day but i forgot they have the dimension but thank you
Aaron

I found these and thought i should post them

I'll give you a couple of suggestions that help.. when you
get done building the headers cut the flanges so the end tubes
are free to move... and on each tube drill 1 hole larger so
each section of the flange can grow and move

Call TTI or Hedman and see if they will sell you flanges.

Nice. Several tube sizes too. Of course you can change the opening size to match your ports and tube thickness.

John, did you ever finish these headers? If so, got any pictures of them?

I used the headman flanges over the winter to make headers for my car and they didn't match the -1 ports very well. I ended up welding them up and and matching them to the heads.

We always cut our flanges and never had a leak, my 2 cents.

We always use SPD for flanges.
