Can you still get header flanges for 3400 heads at W-Tech,didn't see them listed ?

It doesn't look like it.
I should have some more made... I designed mine to be different than most other offerings though. Mine weer individual for each cylinder, and not tied together. -
Did you find an advantage of the individuals over one piece ?Comment

Yes, I always ended up cutting apart linked flanges due to thermal expansion. I have had less issues with developing leaks using individual flanges than linked flanges.Originally posted by Hard Driver View Post
In the case of the gen3 660 it also meant that no modification of the exhaust gasket was needed.
This a header from the last set of headers I built for my LX9:

I've been running the S&S straight flange for years now with a set of stock gaskets (never used any silicon addition) only cleared for the link bars and never had any flange leaks. Granted I've also only ever run alen head cap screws and never had those loosen or fall out, I've heard of many who can't even keep in a set of locking studs. I guess everyone's experience will vary.

Nice looking headers, how thick are those flanges ? S&S is that a brand or stand for stainless steel, got a pic ?Comment

S&S was a brand of headers made for the Grand Am... They can only be found second hand now. I don't know the flange thickness off the top of my head but I can measure it when I get home.

My platform is an S blazer 2wd ,using a 3.4 block / 3400 heads / turbo so I will have to fabricate headers. I have been gathering parts over the last year or two but I had other projects / priorities.Comment

Nice, where did you buy the pipe, do you remember the diameter and gauge ?Originally posted by The_Raven View PostComment

Yeah, http://www.britishcarconversions.com The same place that makes/sells the flanges.... Marc is the owners name.... I'm almost positive he made a tool to put the D-Shape on the pipe... Altho,,, they are not listed on the site,,, I'm sure that an e-mail to him would get an answer... There are posts on this site about it... There are also posts here about making the D-Shape yourself,,, a lot of work... I think it was SuperDave that did it, not 100% sure tho....
Good Luck,,,,
