Yet another header questions for my 71

[Jayschevy]

I've been searching and looking at post about headers for hours now. I've looked so much I've confused myself.
I have a 71 C10 with a 350 5.7 motor with a 350 turbo transmission that was manual but now has a shift kit installed.
I'm bagging the front of my truck and need to know which shorty header will work with my truck without having to modify anything. I need part numbers of headers that have worked for you guys straight out the box and don't interfear with anything else on the truck.
I'm planning on running my exhaust pipe outside the frame just above the frame bottom.
Any help would be appreciated. I need to order my headers ASAP so I can finish my exhaust system.

Thanks
