B35 vs. L-Jet Manifold

[scarey]

Hi All,

I have been searching, but there doesn't seem to be much solid info on manifold flow differences.

I know that there are port size differences between B35 heads and older, same with the manifolds. Will putting an L-Jet manifold on a B35 cripple (sorry to be dramatic) the motor to a noticeable degree? I realize that they used the L-jet manifolds on the Euro motrs, so I know they flow alright.

Essentially, I have both manifolds and set-ups ready to install into the car, but I have been vascillating while finishing up other parts of the project. Now, it is go time and I really am having a tough time deciding. What say you?

Not only does the B35 manifold have larger ports, they're shaped different. B35s are more of a "C" shape, wider and shorter than earlier ones which are more of a square shape. I would either rework the L jet manifold or use the B35. It's different for a reason.
