Valve job on os valves

Yeah it runs in the family just with bigger engines my mom has a 73 duster for her first car and my grandpa has a 73 challanger 383, 69 charger numbers matching 383.
I got my dart when i was 15 and have been fixing it up for a little over a year now.
I'm impressed you don't want to throw it in the ditch for a V8.
