does anymore make a turbo header for an a body?

I have never head of one. It's a really difficult proposition — the headers are already super tight to the inner fenders, and now you are trying to stuff a turbo into each side, plus run more plumbing up to the intake, and a separate cold air intake for each side. On the other hand, it's an easy packaging situation with a slant six. A B- or E-body would at least give you some room to work.
