Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
did you check that theres preload on every lifter? Preload will decrease/clearance will increase as the engine warms.

Did you turn the engine over to tdc on the compression stroke of each cylinder before installing each pair?There was preload on every lifter. I have no way of measuring how much. The instructions just said to torque to spec, which I did.
