Don't go small unless u already have valves etc
Not that u need a 2.02 to make 300 HP but they will certainly aid in your goals.

I'm some what confused here, I've been reading as much as I can about this and from what I've read 2.02 valves hurt port velocity and that's what I read to get to my goals. The engine will probably never see more than 5,000 rpm's.
