Those formulas make real world numbers on the superflow I use,stock configuration heads using stock valve locations and angles about 99% of time will make within 5 hp of formula.
When you get into raised runners,18 degrees etc, spread ports,big chief style etc. then they make more than calculated.
LS engines I don't have any dyno info on them,don't know if will just make calculation or more.
I always check head on flow bench when I know I will run a engine on dyno,so I know what hp to expect.
as example a small block i had heads went 275 @ 25'' calculates 594 made it made 596.
