hey h-t. I was about to install some rocker arms on my gsr head and realize I have 2 sets that are different. Anybody know the difference between the two? These two sets are supposedly from a gsr head. Notice how one set have pins on both primary/secondary rockers and other one only has 1 pin. I tried searching around but can't seem to get any info on it. Anyone have their rockers laying around to check or have experience with the two sets (b16/b18?year?)Thanks in advance.
