i just bought a used set of TODA Valvesprings (16 inner/16 outer) from a fellow H-T member but i have a question, does it matter which ones goes to the intake side and exhaust side? cause on the ITR Valvesprings, they have a color code on top of the springs like yellow for intake side. i asked the guy but he has no idea cause he didn't do the install. if anybody could help me please?
