Are you planning to run full throttle frequently, run a radical cam, and are willing to take a drastic hit in low end and midrange torque in exchange for a 10% horsepower gain? If so, go for it. There's no free lunch in the performance business.

I'm actually planning to do a lump port modification on a 230 engine, along with a set of oversize valves and a lot of porting and polishing, but the engine is headed for a very lightweight Excalibur fiberglass-bodied roadster. I'm planning for a 6K+ RPM redline with three side draft carbs and a pretty radical camshaft, so the engine will spend very little time in the low to midrange RPM area. I'll also be doing some extensive tuning on a bellhousing dyno before the engine goes into the car.
