what turbo headers for a 318?

So im contemplating a mild twin turbo setup on my scamp. Cheap ebay t3/4 hybrids. My motor is a 74 318 that I imagine is all of 8.5 to 1 compression. I plan on using a fitech or sniper from pace, and only running 7 or 8 psi. I imagine the teen will live just fine as long as its not wrung out or pushed beyond that. And heaven forbid she goes....not like its a virgin 340...

But I digress. something I see almost no offerings on is turbo headers. I know mopars can switch left to right, but dont seem they can flip vertically.

I see magnum truck shorties, and I see sbc turbo headers. I imagine cutting off the sbc flange, and re welding a mopar flange is probably just as Easy as having to take a magnum header that is pointing downward and weld on a t3 flange and figure out how to point them upward...anyways. thoughts on the lesser of evils header wise?
