SBM Edelbrock/Speedmaster Head Data

Are you taking air speed readings at all? Curious what the air speed at the pinch is, middle of port but at the pinch, before the dip, middle of dip, and after dip? If you can, also check air speed at the roof over the short turn in those lift ranges too.

Here's the velocity numbers. The numbers on the floor are taken with the pitot right against the floor. At the apex, the numbers on the floor are actually taken slightly around the turn from the apex. I was searching for the highest number I could find at the time. If I take the pitot all the way to the right (cyl center) at the apex, the pitot reads 0 if pointed at the intake opening. Velocity in that area is all vertical, from the roof down. This is one area that needs work.
