im rebuildinga b18c4 ukdm (same as b18c1), well the valve springs are dual blue ones on the intake and looks like single brown on the exhaust side. i have another set of valve spring from a b16a and was thinking of putting the dual intake springs on the exhuast side of the b18 head.

only problem is the colors of the b16 valve springs dont match anything ive read on honda-tech , one side are green, and the other are red it looks like. any one seen this before ?. or should i just had the inner springs to the original b18 exhuast springs ?.
