I have a 2002 z28 any ways i just got some new lifters for it because the old ones are out... they are gm part number 17122490. The pushrods i believe are stock length but beefed up(previous owner did this upgrade). also i have some ls6 springs i plan to put on... do i have to preload these lifters or what? If so how would i go about doing it. Oh yeah stock rockers too.
