What do the colors mean? When I took apart my z6 head, I noticed that the exhaust side had green color marked springs while the intake side had orange color marked springs.

I am just wondering because I noticed that a few of my intake side springs where green and a few of my exhaust springs were orange. Would this in anyway effect the head? I'm just a bit confused about the whole coloring etc. Anyone chime in? Thanks

 

Noone knows anything about the spring colors?
