Percent of lost lift due to 58 degree lifter angle?
Honestly, I'd just say run the strongest components you can afford and don't overthink it.
If you're really worried about that 30 thou, just go one size up in the cam.
Next time you're looking at a ruler look how small the 1/32 increment is. I'm not saying it doesn't make a difference in flow and/or power output, but honestly it probably wouldn't be much.
