Best Seats in the House

My dad(retired) enjoys working in the garage everyday.  He spent considerable time cutting my valve seats.  The seats were a bit deep, so we went old-school, and cut down some shovelhead intake valves(which are larger) in the lathe and relocated the valve seat farther out.  It works . . . sometimes.  Other times it's best just to machine out the old bronze seats, and press in new steel seats.

These late-model valves have an improved shape too which should help flow.  I'm thinking maybe an Andrews AB grind camshaft?  Mild with a slight boost where I want it . . .
