Has anyone else tried ported heads with trex cam? I just swapped my stock 853's for stage 3 dimple ported 243's. Since the cam was designed around stock heads I used a stock casting with stock valves. Heads still flowed amazing on the bench. My question is has anyone else done this? If so what were the results?

Do the dimples create the same effect as a golf ball? Like as in air is able to flow over and around the surface better? It just reminded me of that and was wondering if it is the same concept.

If you want to get deeper into the aerodynamics, there are two types of flow around an object: laminar and turbulent.dumLaminar flowdumhas less drag, but it is also prone to a phenomenon called "separation." Once separation of a laminar boundary layer occurs, drag rises dramatically because of eddies that form in the gap.dumTurbulent flowdumhas more drag initially but also better adhesion, and therefore is less prone to separation. Therefore, if the shape of an object is such that separation occurs easily, it is better to turbulate the boundary layer (at the slight cost of increased drag) in order to increase adhesion and reduce eddies (which means a significant reduction in drag). Dimples on golf ***** turbulate the boundary layer.
