Folks, you can take pics of cylinders till your hearts are content! The motor guys on here are not going to be able to tell you anything except "yeah that's been ground on" if you don't provide us with port window sizes, heights, and widths. If someone on here seriously looks at one of these pics and goes "Dude, thats a radical port job!", then they don't know shit. We need specs to tell you what your motor may be ported to do. Even then, pipes, compression, and intakes are going to affect what the motor runs like.
