which one would u use on a daily driver with a good punch to it?
For best punch below ~3000 rpm, go with the round-port heads. For punch above 3000, go with the oval port head.

The closed chamber is good for maybe 3% extra power (if you use the 10% more expensive 'premium' fuel), and it helps increase both low and high speed power. Somewhere around here is an analysis of the compression ratio difference.

Guess: the oval port head will give more high-speed power than the closed-chamber round port head.
