I just put type r valve springs in my gsr head to compliment my type r cams. However, the intake(yellow) springs were put in the exhaust side and the exhaust(blue) springs were put in the intake side. My question is, will there be a performance problem or motor damage because of this? Please help, thanks.

 

Anyone....I need an answer

 

right off the bat, there will be a performance problem. if you rev it high, you could potentially float intake valves.
