Good Cam Choice?

To claim a 30* intake seat is useless is just ignorant. The 30* intake seat is beneficial to about 400-450 lift. High hp engines are using more than 450 lift.....
Many folks will use a lower valve lift for a variety of reasons. Working to a budget, cannot afford new springs/head work for more valve lift, happy with a modest hp increase, want to reduce stress on the valve train, etc.

See below, Edelbrock Pontiac head converted to 30* seat.
