if oil pressure keep building, then hydraulic lifters keep valves open. so yes I guess valve float is a reason why. if you wanna increase your revs, you need solid lifters....Tom's motor can easily rev out to 10k without worries.
Not to mention with a solid lifter, the cam profile can be more aggressive (ramp rates and opening times), solids will make more power.

an ideal valve seat cut would be a smooth radius for flow but since that's virtually impossible to produce for cheap, shops will cut a series of angles to simulate the round edge. the more cuts, the closer the approximation is to a smooth curve.

My head has the shim under bucket conversion as well, but it's actually the theoretical risk of water pump cavitation (as well as general engine longevity) that has me keeping the redline <9k rpm. Not too many people have been there so hard to say if it's an issue or not, but it'd suck to kill the engine over 500 more rpm when 8500 seems like plenty, especially when the torque starts dropping off after 5-6k based on dyno charts.
