Yes but valve clearance also depends on valve even times. If you do a little trigonometry you can figure out exactly your valve clearances at different degrees of crank angle. I was just thinking what your IVC time must be, for 12:1 SCR (assuming SCR) then you must be something close to 70 degrees ABDC... that or you are running higher octane fuel and a cool thermostat
