Hello good morning friend, I'm also looking for rocker arms, but I don't know if you knew that there are several models and it can be very tedious to find the specific one because there is variation by year and model of the head. Normally you have to know specifically which one is needed ... some rocker arms have the coarse adjustment screw (which came out mostly for engines that had a linear fuel pump) and the other model came with thinner rocker arm adjustment screws (which is the one that has a rotary fuel pump) and they came out for the Japanese market, I'll put some photos to guide you, THE 3B ENGINE HAS MANY VARIATIONS DUE TO THE YEARS OF MANUFACTURE AND IT'S A BIT TEDIOUS TO FIND PARTS FOR IT !!! Good luck friend
