I think I would remove the hood insulator and see how it shuts. With that gone, there may be no interference. I mean, the folks who make the parts probably figured you'd already have tossed the insulator. FWIW, you can loosely wad up foil on top of the engine then close the hood to smush the foil, to see what is how close. Might help. I don't know, I haven't messed with ICs. But I have a pair of those 40th scoops if cutting the hood for them will give clearance!
