Can someone tell me there experience with the 1.3 stamped rockers with a Mod-2. I,m using a .640 carb with .960 pipe w/ muffler. I would like to get a little more power. My normal rpm is 72-7400. Would a ratio rocker on the intake side be good enough since I have the 960 pipe or run the rockers on both. After I install what should be my target rpm's. I have my timing set to 32*. Thx
