Small block TrickFlow heads part 1

Ok I’m going to lose a few guys but maybe others can maybe put things in better words. All numbers listed are FPS (foot per second) my readings limit out at 401 which is to damn fast. The picture is marked top, bottom, pinch, and common wall. As you can see the dinky port entrance maxes out on the whole port wall at the pinch with great numbers everywhere else. 11DCDB17-86D5-40C6-A48E-A937FADA7909.jpeg
