What am I gonna do with these?

These are on my shelf in Michigan. Don't know who made them, or when, but think it was back when the slant-6 was still a current-production engine. Don't know that I've ever seen a set of headers with provisions for a factory automatic choke (and provisions for a heat-tube type automatic choke, too). Don't know what I'm going to do with them; headers are against my religious beliefs.
