Do you really want to use springs that have been on the car for a while when you upgrade the cam? Do the LT4s and 1.6 RRs for now. Replace the springs with new ones when you do that cam! Dont half *** it and cut corners.

Can you guys get that much install height on your stock heads. I know sometimes the LS1 guys can barely get 1.800".
PAC-1218 would be a good drop in spring for you.
