LD340 manifold vs RPM Air Gap

I loved the change from my TorkerII 360 to the AG.

The nice thing about the LD is the generous sized near gasket matched ports with a good plenum amount.

It falls behind on against the RPM design due to the RPM's nicer runners even though there smaller. Which is a key item. Velocity is it on this intake and it's additinal height for a better shot into the head.
