Here is a stock 12A port. It's not rounded or D shaped on the trailing edge (the upper edge). It's important to keep the chamfer on the port edge though.Ghostkls wrote:That is what I am talking about! Wouldn't it make more sense to taper off the top of the port for street applications, which should help reduce wear on the apex seal and increase engine life by allowing the seal to transition into the groove?
When I look at that port, at high RPM the seals are being "thrown" out the rotor so sudden end would chip the seal over time.
