I am using my stock rockers and the pushrods are a cup on the rocker end. Isky didn't recommend anything and I did mill the heads so the tolerances are all jumbled up. I could have measured the pushrod wrong. My neighbors dial caliper was a .200 per revolution and it's easy to be off by .100 if you're not paying attention. I should have screwed the adjuster in further before I used my pushrod checker. The instructions said expose 2 threads but 3-4 threads would get the cup away from the rocker arm body and I would have a little shorter pushrod because of that..... I bet that's it!
