Chris, my mistake, cc's before valve diameters, misread it.

seems like 280 valves are an easy swap? Does port flow/velocity suffer and become a top end engine like an L-88 vs oval port or 2.02 vs 1.94 on small blocks? Boss 302 is the all time worst.

Yes common swap on the small valve heads. Can't answer about the flow or velocity suffering though. Most folks who go the big valve swap also port and polish the intake manifolds as well. So that really changes the variables.
