Bisi knows more about getting NA power out of the F-series engine than anyone on the planet, so I'll take his design over someone else's guess any day of the week.
Notice the exhuast duration is much lower than the intake. It will cram a massive amount of air and fuel in there but the exhaust valves are still going to close in time not to cause a loss of vacuum on cylinder filling (SUCK). That's why the offset is such sweet design. I basically got the race spec intake duration with the moderate street spec exhaust duaration.
