For all practical purposes the cam does NOT deflect, even with an .820 diameter relief between lobes as with a 404. This is with valves at 100 lb. on the seat.
I have watched a 404 with a strobe running in a test fixture at 6500 rpm and all you can see is very slight flutter. Almost imperceptible. This was a cast iron core. The steel ones have even less flutter.
