273 Headers (weird combo)

I've been searching for a few hours now and I cant seem to find a great answer. Have a 71 Dart swinger, 273 with larger port heads on it. Power steering is stock and I'm trying to maintain column shift. Its a 727 trans and I will have to use an adapter to cable style. Its a conversion car so /6 k member. If I look at headers for the 318 or 340 they should work with the larger port heads correct? I see TTI is probably the best option but these are kinda temporary so wondering if any cheaper brands will work even if I have to fight with them. Any help appreciated.
