one quick little question before im done with this thread fellas, i started thinking and i confused myself(always happens to me) well i think i understand everything else port width where to bend etc... but when im bending port length, ex. lets say i have 10 inches do i bend 10 inches to each side, or do 5 inches to each side(which means i devided the remaining length by 2)? thx again guys i know i can be fustrating but im in learning mode.
