i tried searching but this is kinda hard to find so hopefully someone who knows can give me a quick answer. I have a bag of d16z6 valve springs and they all look identical. Is there a difference between the intake and exhaust springs? i know that in some of the d series there is a difference... and i couldnt find anything in my manual that says they're different either.

And which end goes on top and which end goes on bottom?

for an answer
