Which valves needed for Hot Cams spring Kit?
My 04 KX250F need intake valves. Does this kit work for stainless valves which are slightly heavier or is this kit for the titanium only which require less installed spring tension which have different spring requirements ?

I have a 01 raptor 660, so how many would I need to replace all the valves?

This is a complete valve spring kit and would include the springs to do all 5 valves for your 2001 Raptor 660. You would only need to purchase one kit.
