But it seems like a lot of guys are looking for this setup.

There are two different lengths for those, I wonder which ones that those are... The "long" or the 'short' ones....

I have a difficult time telling too. I think those are the long ones. The short ones are the ones you want for the street. It's hard to tell the difference without being able to look into the ports.

The short ones are the ones you want for the street.

A vacuum booster isn't a bad idea with those, either.

Those are defiantly the long ones. The short rams runners are not divided for 15" closest
to the head. The short ones are the rarest and a one year part that were intended to create
the charged cylinder filling at a higher rpm than the standard long rams.
Exhaust manifolds are even harder to find.
These were not really designed as a race part but more of a way to give a heavy
Chrysler 300 some extra power for passing at the new hiway speeds of the early
60s.
Best to get all the parts as a set. Hard to piece together.
