im putting together parts to rebuild an ls block with gsr pistons i was wondering what kind of piston rings you guys suggest/ have experience with.. i saw a set of ebay rings for around $70 a CP rings for aroung $150.. i dont mind spending the $150 but im wondering if its even worth it. its just a basic rebuild (bearings & bolts) and gsr pistons. setup will be n/a ls/vtec with bolt ons.. lmk what you guys suggest/ have experience with.
