As a matter of interest, what tining is usually attained with a stock camshaft in place? Seems to me valves unlikely to be lifted free of seats at 0 40 45 15 timing claimed. Clearance accounts for a remarkable amount of rotation, and unless my 4th form trig is rusty 10deg of cam rotation seems indaquate to cover both lift and close, unless clearance just .002.
