Hey, I just installed aluminum 1.9 roller rockers. I believe they are older Yella terra's. They are anodized red and each two have their own pedestal. I installed them with the comp cams bolts and torqued them down to 23 ftlbs. They seem to be fairly noisey. Im running them with #90 springs.
How much louder are they supposed to be over stock? Any help would be appreciated.
