8BA valve seat grinding

I think I’ve sussed it. Just needed to go a bit deeper with the 30 degree first.
One final question, how far do your valves normally sit above the deck height once set?

Sinking the seats will somewhat restrict airflow as well as take life out out of the block unless you want the expense of replacing the seats.
