Overheating -- Corrective measure questions.

Another thought that came up when removing the shroud. I have a chin scoop that completely blocks air flow under the bumper to the radiator. Should I remove it or drill a dozen or so 1.5 inch holes to direct air up to the radiator? Will it make a difference? I am awaiting a new radiator, water pump, Crank pulley ,WP pulley and shroud.IMG-0974.jpg
