Im building my valve train up and I want to know what locks and retainers you would use with pac 1218 springs and a cc305? thanks

 

i think the comp 774-16 steel retainers will fit those. as far as locks, are you still using the stock Lt1 valves?

 

i have a brand new set of comp 787-16 retainers forsale..40$ shipped..i was going to use them with ls6 yellow springs to give me .550 max lift on my lt1 heads..but im swapping cams an got a set of .600 lift springs that came with retianers.
