Ford 289 Valves for /6 - what a deal!

Yeah, but I'm looking to reduce inertia power-loss. Matching this springs with lighter valves, Wiseco pistons, Ferrera lifters (65 grams each), and tool-steel retainers will get me what I'm after. When looking at each part individually, it's overkill for my engine, but the cumulative effect of the parts is what I'm after. Not as much in HP/Tq as a free(er) spinning engine with less operational load. Not a common approach for a slant, but it's my direction.
