Looking at the top of the rocker the left rocker arm adjusters are offset to your left side, same on the right hand ones. Number one cylinder has a a right side rocker arm on the exhaust port and a left hand on the intake, # 3 cylinder is the opposite with the intake beig right hand and the exhaust is left hand, the adjusters are closest to each other in the middle regardless of cylinder numbers I would, and have, send those rockers back to Harland Sharp and ask them to repair them for you they have excellent service and they may rebuild or replace them for a very small service charge, maybe no charge
