First of all, you’re awesome for wanting to get that deal on the road. Kudos to you and your good taste.
Second, stainless and cheap are never seen in the same paragraph, let alone sentence.
I have a 66 Squire wagon with a cheap set of headers on it and it’s a pain. At first I tried to find a gasket sitch that would work but they all blew out after a while. I took the passenger side header off and checked it out (BTW they’re just cheap block huggers from someone). Had to re weld around the collector and add material to the flange in order to be able to make a flat surface. But now it seals.
I’ve yet to do the driver side.
If you’d like I’ll get you the name of this set when I get home (they suck but with some work they’re ok) but you can prolly find a set of block huggers in the Summit catalog.
If you’re going to make a set, a company called SPD has some really nice flanges and stuff.

I haven’t found a set of ready made headers for wagons but there must be something out there somewhere. I seem to remember talking to FPA about it but I’m to beat to remember anything right now. Good place to start though.
Good luck.
