The opening angle and timing are minus the ramps indicated. The timings are given in EÖ (inlet opens in crankshaft degrees before TDC), ES (Inlet closes in ° after UT), AO (outlet opens in ° CA before BDC) and AS (Exhaust closes in ° CA after TDC).

Since Hydro cam no valve clearance occurs, match the strokes indicated the actual Elevation values.
