Gene, if I'm not mistaken the tunnel ports don't have heat risers in the intake, same as the High Riser intake/heads? Also, the BIG intake runners/ports make it more difficult for fuel atomization until the manifold gets good and warm.

I think these type of manifolds would be a seriousl problem in cold/winter type weather.
