I only was thinking about lengthening the secondaries as its easier.
 The logical place to cut would be at the first welded joint up from the bung where everything is pointing straight at each other.

I don't think you'll see any benefits to doing so just because the primaries are far more important than the secondaries for base scavenging.
What I would do is cut the point before the primaries join get a u bend SS in the right diameter cut and bend it so the pipes sit on top of each other like a 4-1 and pull them out about 18-30"s and use the existing merges as a way to terminate the pipes. |

 A lot of fab guys hate coming in and trying to piece stuff together from an existing part - they seem to look at it as fixing the previous guys screw up. In the end the labor to piece together cost more than building from scratch.

But hey, if you want to build another part with no appreciable gains for the hell of it.  The only way to know is to try, worst case you cut up a relatively inexpensive header and waste a few hours.

Well last update for a bit...I won't be able to start up on this project until next week as well as I need to get a few flanged cut to mate the 2 sections of pipe to allow installation. Again I wish I would have chosen a 4-1 design soo much easier to work with. I say this because the header path has a kink to the left and a quite narrow path that it needs to fit in.

Wow...
 Man, that's absolutely beautiful work.  Are you using a jig, or the car itself for test fitting? |
