Will the .125" make much difference?

It looks like on the heads I have, a 2" hole is not going to leave much surface for sealing.

Can you burn a couple of sets out of 304 stainless




Why 304? Cost? Hi temp is better? Expansion less? Or what?

The only reason is I like 304, its good quality but
if he has a different SS thats fine also... just
as long as its stainless, this time around I'm
building stainless headers

Yes there is enough to make a order. We have some 304 and 316 stainless drop. We will burn them out of 304. The stainless flanges are going to be a bit more expensive though. your looking at $37 a piece (because of the material and because of the small order.)

Everyone please email me your information and I will give you the address to send money orders to. The flanges will be done by the end of next week. So you can have them 2 weeks from today :banana:

Cluthcer I did get your info.

Thanks for your interest guys

No problem. I'm glad I can help.

If anyone else needs flanges let me know. We will be cutting them sometime next weeek. These are top quality laser cut.

Thanks to all who participated

I'm getting lots of W8 questions if these flanges will fit or not. So here's the dimensions.

Yo.... I hope that is not the drawing you are using to have your W9 flanges made from.....

That is Schoenfelds 2" W9 flange. Well guess what, like Aaron Yates suggested there in another post, they don't fit good at all. The shape & size of the "port" on the flange leaves aprox .020" or less in some cases of sealing surface on a W8/9 head especially in the corners around where the notch is to access the head bolt holes.... I have a set of thsoe Schhoenfeld 0408 flanges sitting here on the desk & just had them on a W9 & W8 head..... There is no way I would ever run that flange.

Now, yes that IS the correct bolt pattern for all W9 heads (NON RP) & all "circle track" W8 heads like Steff has etc. So yes it will bolt on, but it will not seal.

You shoudl be looking at Schoenfeld 0407 to make your flanges from. This fits the port/head much much better....

If you want to see some pics of Why the 0408 flange does'nt work well I can go take some.
