I would like the flange to be higher but I dont know if it would help the port flow better.

Ya the first thing I did was flip them.I was thinking moving the bolt hole down to raise the tubes.
edit:I use a scrap pipe to practice and it is not that hard to hammer form to a square so I will index the center top of the pipe and give it a try.
edit:here is how the pipes will go but the center pipe will loop over and down into the fender.

I know this is not much but I did make a little progress.I have to get this together to figure the #7 for going over the steering column so they all lign up going through the fender.

I need to stub the 3/5 pipe after the bend over #1 to loop it down into the fender.

Looks like you are moving along. Did you see my home made clamps I made to hold the tubes together so you can tack weld them. It's just some scrap aluminum and hose clamps but works great.
It gets real tight on the passenger side by the shock tower. That's where I had the most trouble.

whos kit is that????

Thanks guys!The kit is a heddman but for a roadster,I got it just to get started.
Fastmop I will look at yours again for the clamp bands that will be helpfull at this point with checking the exit angle through the fender and past the wheel.I just opened up a hole for the pipes to come through.I see those clamps I have a couple small pieces of exh I was going to split and do the same thing.

I am going to have to mock up 4 tubes in the collector to check things out better[exit angle,fit.]

The tires on the ground and I turned the wheel all the way to check where the tire would be.I will have to add some room for suspension travel.
add on edit:

this is the #1 pipe testing for length,angle of exit.

I am thinking of vee banding the #7 header tube to make the headers removable to get past the brake MC and equal length.your thaughts?

I think I made some progress in the puzzle.

Thanks for the positive feedback guys!The options you listed are very helpfull for the #7 pipe and taking my time on my choices is just my way of learning in the process so I hope you will be patient.Greg the #1 pipe would actualy be longer I believe going over the shock but not by much and is an option but I figured I would try another way to be sure what I wanted to do. I may make the slip joint at the collector to help with taking it all out from time to time but I think that will be the last adjustment to the system that I do.I am going to work on the 5,7 pipe this wk now that I have run some pipe out the fender.
edit:here is a better pic of how they come togather.

I am trying!

I am sure that is a miserable job, trying to fit all of that in such little space. hats off to you.

I dont know what the other specs are of your engine but it doesnt look like you will be able to remove the valve covers without removing the exhaust. That would really suck when you need to adjust the valves and I dont see how you will access the plugs either.

not trying to but I have considered building headers and never grown the cojones

I made sure I can remove the valve covers.That #5 pipe will be away from the covers more when done.
