B-RB 3690933 spring what retainer?

Thanks, I will look into this once again....The springs other than the ones you mention and the ones recomended in the Mopar manual seem to come up as 5/16 valves?
Just dont know, this cam is a regular 440 HP, and I want to use the springs the manual calls for yet the retainers the manual calls for dont work with stock 3/8 valves? What am I missing here?
LOL
