Using the same wide intake BGF. Had to replace the piston/jug because there was casting flash that broke off from a port that was never chamfered. Bought a replacement wide intake jug from BGF. This time i cleaned up the ports and chamfered the edges. I also filled the bottom end with seafoam to clean out all of the debris. Lots of metal shavings/dust came out.
