BC valve springs & retainers

i am looking into getting a set for my JDM b20b with p8r head (also wanting the stg 2 cams)

my question is, are the LS BC valve springs and retainers usable in the P8R head

i search and couldnt get a good answer:read:

i’m not 100% positive, but i’m fairly sure they will. don’t take my word for it, but i would assume so.

don’t OEM LS and B20 valvesprings have the same part numbers?

if THOSE are interchangeable, i can’t imagine why the BC springs wouldn’t be.

BC= Buddy Club or Brian Crower? just curious. i would assume Brian Crower, as i don’t believe Buddy Club makes non-vtec springs.

brian crower

sorry for the confusion

thanks for the input
