Valve job on os valves

well i did for a while espicly after getting my grandpa to floor it in his challanger as it has a stout motor (383 stroked with a 440 crank cam forged ect...) but i got real tired of the never ending line of v8s at every car show.
It's really boring, isn't it? I've had the most fun ever since I went to the slant 6.
