I have a 00 LS1, so far it only has bolt on modifications (LS6 intake, headers etc) I picked up from a local shop a perfect condition 02 LS6 cam and a set of 01 LS6 heads. I know that the 01 LS6 heads dont have the lighter valves but are they the same length as the 02+ LS6 valves. Also, the heads have a brand new set of LS6 yellow springs. Should I go ahead and switch them out for a set of pac 1218s. I was told that the yellow springs will not work with the higher lift 02 cam and the solid 01 valves. I know I could have went with a bigger cam but so far between cam, and heads i have 150 bucks total invested. Im not looking to break the dyno record when I get it tuned, I am more interested in the swap itself, not the end results. Thanks,
