We are going to install the heads tomorrow with the push rods and rockers. As i was cleaning the rocker arms there was a number stamped on each one. What is this number? Do they have to be paired together any certain way?? The rockers are 66 289, non-rail kind. the numbers are 10, 18, 43, 87, 93, 121, 129, 150, 153, 167, 176, 180, 182, 242, and 255. what are these numbers?? Do they matter? I know that was only 15, i cant find theother one yet, opps!! Thank you very much, Adam.

I just went and looked at mine, they all ahve numbers on them which do not all match yours, I have some of the same numbers. But there does not seem to be any pattern. Hope that helps

Adam, those are manufacturers production codes. You do not have to install them in any particular order as SBF rockers are the same for intake and exhaust. Alex
