when using a leakdown tester do you have to remove the rockers?

No but the piston must be at TDC with the valves closed.

No.But the piston must be at TDC on the firing cycle.You will find this very difficult w/o a degreed balancer.If you do,I like to start at #1,rotating 90 deg
between cyls through the firing order.
