I thought I would start up a new thread but with the details about my installation of the Vick Auto header install on a highly modified car. So after many years my IAP header bit it for the last time. I can't remember when I got it but at worst case its 25 years old and has had many mods and repairs over the years
This photo shows the final straw:
Yep it is very broke.
So after contemplating fabbing up a new one out of Stainless or buying a Stainless Honda header and modifying it to my needs I took a look around and found Vicks had a very good priced header near my specs. So I ordered one up. For me this was going to be a Saturday morning remove and replace (remember this comment ) . To fab one it would have cost me about the same in just the metal before forming cutting etc and bending SS is no joke, SS does not want to bend and has tremendous spring back. So this is how arrived :
**THAT CLAMP IS NFG - don't use that. Only if you lost a bet would you use it. It crimps the metal together and you cant get it apart if you ever need to service it.
So similar to other SS headers I have purchased that came from China the quality was right on. I built major power in my Subaru with a similar product and it was fantastic. Some pics of the welding:
Here are some specs
Tube ID is 1.228in /1.355in OD
Collector Exit OD 2.376in ID /2.5 OD
Thickness is about 0.062"
Length flange to collector is 35.5"
Here are some general pics of the construction:

All pretty good cept one thing, Problem1 the collector exit is 2.5" and my old one was 2.25". Bitter sweet because it is likely better but now I have to rebuild the muffler with larger tubing. Fortunately the muffler was a 2.5 tube that I was able to save it.
So it began by cleaning up the ID of the welds at the flange:
Problem 2 was the O2 Sensor just happened to be positioned where I have my anti-roll bar.
I have a PBS style bar so I have no idea how it fits with and Addco or other bar.
Time to break out the equipment - normal for race configurations ;-):
O2 sensor and V flange sub assembly:
Coming together:
A bit of trouble here - ARGH! Number 4 tube is quite high. This has always been a problem with the side draft configuration and my manifold has been milled with a slight up angle and cleared around that particular tube.
Fit up, yep #4 not looking good for me:
There it is - Drat!
So I had to break out the MAP gas and heat and beat the tube plus some hogging of material on the manifold and a bit on the carbs but in the end it all came together nicely - there is a thin aluminum heat shield that is later sandwiched in there too:
New muffler bits:
It is now back in the game. Some teething pains (self created) but it came together as expected. My install I would say is not typical and for me this header was a major solution. I will add more in another post about some of the other details but I am quite happy with it.
