Trying to find a way to determan which head is which. Is there any #'s on the head itself? I know the block codes. But I am having a difficult time when speeking to someone over the phone. Any help would be great, Thank you in advance.

yes... there should be the same 3 letters stamped all over the head

PRB = dc5-S
RBC = fg2
PRC = dc5-R
RBB = cl7 (tsx)
RRC = fd2-R
RSP = fn2-R

there are a lot more base not listed :silly:

here are a few pics of my '07 si head
