I didn’t think so, but saw this comment. This set kept popping up when I was searching. I guess take it with a grain of salt.

Ahh, I guess I should default to the 454 folks on this one. Thanks for clarifying. Now I’ve only cluttered the thread.

I think we have a thread on long tubes. I’ll try to find it.

I have a set of longtubes on the dually. The ones referenced look like squarebody big block headers. I know for a fact those won't work, I have a set in my possession.
