My stock springs had about 100k on them when i put my 1.7's on originally. A few months later, I noticed that my valves were floating at about 5300 rpm and higher.
I put on a set of comp cams springs (about $70), which installed very easily, and the problem went right away. Also the car seemed to pull harder on higher RPM's as well.
