Good, sure.

Best? I don't know.


What size valves, billet head, what size/flow carb? 308 with stock rockers sounds kinda small to me, but if you are running a stock carb and head, it might be enough. Even then, the additional cubic inches of the crank would make this engine combo very asthmatic with a 22mm carb.
To me, I'd rather build the engine "bigger" and make more power out of it then try to hook that power up. I've never met a customer that cried about having too much power. :)
308 with 1.3:1 ratio rockers sounds like a good combo to me with a good/big Mikuni and some decent headwork.
