Thanks for the responses. Glad I'm not alone in my logic. Just making sure I was thinking the right way about it. Those valves I got on a killer deal, so I just snatched them up. I picked them up for $500.

On another note. The valve springs on the intake side are the same as the exhaust (most likely not the spring rate). I'm curious if anyone knows the specs on them. If there's a way to eliminate the valve float for another 500rpm, I believe there would be a benefit having that extra rpm with the right cam profile and maximizing the ported heads.
