First...you ain't gonna find any headers for a Galaxie for $200. Only popular, high volume, price leader headers go for those prices. Even used they go for more than that. Raise your budget to around $500 for new or $300 for great condition used.
There are headers in Tri-Y or Shorty configurations, they still cost close to $500 (~ $450 - $470+ accesories). They are easier to fit, give better under car clearence, but are not much cheaper.
Yes a 410 is basically a 390 with a 428 crank and different pin height pistons.
