Just finished doing a set for a friend of mine way too many hours and frustration to do this any more let more talent people do this. His car was a hard one to fit the tubes into.

I built my own, I would do it again in a second. Loved it.
Brutal tight area and 2 1/8" primaries, I made spike collectors and equal length tubes, fit like a glove!

Nice welds though!

I like doing them... sometimes its a bit more time to get them as close to equal length as possible

I know of dyno tests that indicate equal length is unimportant. I wouldn't spend my time trying to make them equal length. Make the bends as smooth as possible, that is more important.
JD, those headers you built are art!

JD, those headers you built are art! Equal length is like port timing.. I try to get it as close as I can.. I seen it on the dyno.. on my W-9 set is within .1 in length.. but what do I know

My friend Jay Brown was meticulous about always building equal length. Then someone told him smooth bends are more important than equal length. He didn't really believe it. He has his own dyno, so he did back to back tests. He reports to me that equal length didn't make any more power. But you have your own experience, go with what you know.

Smooth bends are a standard.. you have to do them if you want any decent header.. but equal length is important also EDIT Also if you can you want large radius bends.. but number 1 thing is they have to fit in the car

Never again? That would be a shame. Looks like you did a nice job.

If I were doing them for a living there's a plastic tubing kit where there's a ton of curves and straights that snap together and make each tube (all four at one time). They come in different size tubes and allow for any bend and really look like a header when all snaped together, infinitely adjustable. They start at $245 and go up, no more guessing and trial fitting. Isn't that the kit that you send in to have the pipes bent to there shape?
it's ok to butt heads, just don't do it with a butthead

Yea and no. Stainless Header Co. has jointed pipe kit you can use for a model so they can make make a header to your design. I suspect if you had the ICE kit they'ld be fine with that too. But you can buy the ICE blocks for your own projects too. My impression is that they can be helpful but are not magic. It probably depends on the builder and the specific situation. Brian Slowe built me a set of headers last year and in this case he did not use them (even though he has them). Here's a post about them over in Speedtalk. http://speedtalk.com/forum/viewtopic.php?f=1&t=41836&p=565969#p565969BTW That's a great thread to read in general for anyone interested in headers, at least the first 5 plus pages anyway. Lots of points about building as well as design and theory all mixed in.

Hot rod did a test (is a you tube videos of it) where they did back to pulls on a set of headers. Then took a hammer and beat a dent into a tube ....made a pull...more dents...a lot of dents. And I think was like a 6 or 7 hp loss. And the headers looked like junk

And I think was like a 6 or 7 hp loss. And the headers looked like junk I watched that some time back.. I do have a couple of questions on it.. first.. if a bented up set of headers works just as well.. doesnt that give you the idea that the area of those were to large to start with.. second.. if that held true.. why arent all the pro stocks beating up there headers.. my opinion on that vid is they were too big to start with.. but a lot of people use to big
