Hi guys, i'm new to this forum, i need help on choosing the right v/springs for my set up. it's a bit complicated so i will have to make this a bit long. i'm fitting ITR cams in a b16 a2 head, the spring in this head is :inlet dual with yellow paint marks on. exhaust dual with blue paint marks on. i also have another set of dual intake springs which came off another b16a head, not sure if b16a1 or 2. this set have green paint marks on. i need to know if any of you guys out there know those valve springs by their color. so i will know which ones to use. i will also tell you what i was planning to do in order to help myself. i was going to use the yellow ones on the intake side, and the green ones on the ex side. please advice. thanks.
