Are there any differences between the L98 and the LT1 Rockers and springs? Or possibly the LS1? I'm looking for a cheap upgrade from stock but don't want to spend much money at this time.

EDIT - What about rockers from a ZZ4 Crate engine? are they just normal stock rockers?

 

Yes, there are differences. The rockers and springs that were installed on LT1s were manufactured after 1993. The ones on L98s were made before 1993. Other than that, the springs are teh same old POS 85# units, and the rockers are the same, self-aligning versions of the stamped rubber SBC rocker found on L98s.
