Looking at pushrod cup adjustment on these Harland Sharp roller rockers. HS says no more than 3 no less than 2 threads showing when determining pushrod length. I have an 8.100 on one side and an 8.200 on the other side. Both of these will work. However using an 8.150 is going to result in the best of both worlds!! | Steve V's Automotive
