TrickFlow heads. A few teaser pictures

Ok finally got this head on my flowbench last night. Left column is stock on my bench and right column is after welding head up and opening up the pinch .100. After church I’ll post up numbers after a little more work. This is still with the stock 2.02 valve. View attachment 1715892747

Are you measuring air speed in the port, before and after? What I don't like about that head is how small the pinch area is compared to the short turn "area" and then the 2.02 valve. Kind of weird but if you run a large enough cam they'll make power.
