I was planing on making a custom intake for my L24 in welding. i know that tuned headers have equal length runners to alow for better scavanging, is the true with intakes aswell? will 6 equal length runners preform better? i plan on making this for the Weber DGV carbs since the manifold that came with them suck. does anyone have the dimensions of the intake flange for the E88 head? that would help since my Z is my daily driver. What thickness should the flange be, and what piping should i use for the runners?
