97-03 GTP stock valvespring lift rating?

Was talking about lift at 1.6 rocker ratio which is what 97autoxvette was asking about....stock cam 1.6 rockers is .412 lift...stock cam 1.9 rockers is .490 lift...l76 or ls6 springs will support 1.9 rockers but for what its worth if you keep the shift points under 6k stock springs will work just fine I never had issues and I have seen alot people with the same results
