i did my first port job on my stock cylinder today. i made eyebrows on the transfers. and instead of widening the exhaust port, i made 2 additional ports on either side of the stock exhaust port, which met with the main exhaust channel. making the 2 additional ports, decreases the chance of catching a ring you might get with widening your ports. i was hitting around 37 with a biturbo and 15 bing.
