Ok , I talked myself into this kit as others have. I am buying a ls2 timing set at the local dealer and a new ls1 oil pump. Now do we think its worth it to get new lifters ?? maybe new pushrods?? got 120k on mine. This should make for a nice little upgrade on a 01 and still be very mild mannerd driving around. I will take pics and post results . I will start on it this comming saturday so by sunday I can tell you all how it went. A friend is letting me use his lift so I'm cheeting and dropping it all down fast and easy.
