yeah, put the engine on Z1 for #1 cylinder before removing tensioners. the cams will stay put if you do that, as long as you do not turn them, or pull on the tight side of the chain. when swapping the outer ramps, the tight side of the chain will hang in the ramp grooves, so a tiny pocket screwdriver is slipped between chain and ramp to lift the chain just a hair, so the ramp can be popped out.
