air gap manifolds

[slotracer]

can you use a rectangular intake manifold on oval port heads and will there be any problems with using it? thanks

They'll bolt right up. May not be the most efficient set-up, but it will run.

It's been my experience that most oval port heads will port match to a rect manifold if you use a short radius for the transition.
In case your wondering....

Not pretty...but works.
