They should, I had a set that came off a 300 in a 78 and they fit just fine. If you're really worried about it, though just run the EFI dual manifolds. Those would be better for a 240 anyways since you'll be spinning faster than a 300 typically.

headers are a royal nightmare to install on the passenger side. especially if they are the large jungle gym style ones. the shorty ones probly arent a big deal. mine are cheap hooker competition headers.
