Will this setup front index shift properly?

Road bike with105 9 speed brake/shifter,

5503 or 5504 road front der,

110/74mm triple crank with 46/36/24 straight cut rings-no pins or ramps,

12-34 9 speed cassette with M750 long cage der.

Will I have to grind the cage to match the smaller large ring?
