That's awfully close isn't it. I wouldn't have as much of a concern if it were on the other side of TDC making the intake valve close a touch earlier. Your current setting means the intake valve isn't closing for 3 degrees retarded which reduces your effective stroke until volumetric efficiency spins the motor high enough to accommodate. Dynamically, I'm sure the motor will be fine at higher rpm given the intake/exhaust works well. Lower end flexibility may take a hit, albeit nominal.
