There is no boost creep on appropriately sized external wastegate applications. Some other factors like exhaust scavenging, blah blah. Mostly the wastegate.
I imagine with larger intake runners you would enjoy a little bit less knock/heat and more turbo efficiency. More flow = less boost needed. Remember 12psi @ 500cfm isn't the same as 12psi @ 750cfm, you could run more efficiently at like 8psi @ 750cfm. These are example numbers not actual figures.
From what I know, this motor is pretty well balanced, no issues with factory oiling equipment, very strong crank. Tolerances seem pretty darn good to be honest if you maintain it well.
So just remember that heat kills. Heat is a by-product of pressure. If you keep the heat down, you keep the dangerous pressures down. This is why I'm going with an EGT at some point to backup the wideband and re-affirm running 20+ psi is safe enough (for me).
