i am not sam i am, and i do not like green eggs and ham................. biggrin [i couldn't resist. laugh2]

i have a TTI set # 440-218, which are 2"/2 1/8" for angle plug heads, and are bolted to a set of worked performance RPM eddy heads. these pipes may not be what you need the info for, but this is what i have.
the # 6 tube turns down right at/off the port. the #2 tube is the highest, and sweeps up, then drops between #6 and #8 tubes. #2 tube height from the attaching bolt centerline at #6 tube is 3 3/8".
the height above the top of #6 tube is 2 5/8".
the height above the attaching bolt centerline of #6 tube is 2 5/8".
the #1- #7 side is a near duplicate of the #2- #8 side.
#'s 4, 6, & 8, as well as 3, 5, & 7 all turn down at the port.
these measurements are just approximations, taken with a tape measure, having my old head in an awkward position in low light. hope you can understand what i'm trying to relay with my descriptions.
i don't know if this helps any or not..................."sam i am [not realcrazy]"
