Ported Victor 340 and Super Victor

Yep. Black Gorilla tape.

Here's a question for you guys who have ported manifolds. The leading edge of the dividers is getting down fairly thin, not knife edge thin but thin for a leading edge. In airfoil (airplane wing) design, the leading edge is rounded and the trailing edge is more knife shaped. I only did this because every one of the pictures I see from some of the well known porters are done this way. It is contrary to what 'makes sense to me'. On the flow bench sharp edges can cause problems, especially in high velocity areas. Velocities in this area of the manifold will be a good bit lower than around the valve, so maybe that helps.

What say you all?
