Ended up changing the layout...again. 16 ga. 321 stainless tubing. Got all the primaries within 1/2", which is what took a ridiculous amount of time, while having good plug/flange bolt access, as well as, clear the tire at full lock and compression.

The headers are swept back to clear a brace for the coil over. Just threw this orange piece in to show where that will go:

Very nice work on those headers.. thats the one thing that helps
when make headers... knowing how to play with puzzles.. I do
like the legos

Quick update on available flanges for the Victor head.

The top flange is from Stainless Headers. It is 3/8" stainless. It is literally cut from the shape of the CAD file Edelbrock supplied for the gasket. I know it doesn't affect function, but it is quite ugly in my opinion, and the exhaust port is way too big for my application. They sell for $120 set plus shipping. I'll sell this set much cheaper, just call or email me.

The second one down is one I had made. 1/2" stainless. The port shape matches the exhaust port on the head, which is basically 1.75" tubing. I think it looks the best, but needs a slight trim around spark plug boots, as they touch the flange. This set is for sale cheap as well.

The last one is what I'm going to use on mine. I tweaked the design a little for my application. Still 1/2" stainless. Not as pretty, definitely heavier, but it's for a turbo flange.




I can make a lightened version of the bottom one, in steel or stainless, 3/8" or 1/2", but would need a few ordered or they will be pretty spendy for a single set cut.

I read somewhere they equal length is not as critical with a turbo application.
That being said , you do very nice work , Sir.
+/- 1/2 " is better than I did on my build........I have about 3/4 " difference from short to long and I know how difficult that was.
Building headers is something everyone should try once......just to understand why a quality set starts north of a thousand bucks.
