.600 lift springs and .590 lift cam

I want to go with a Hughes Cam but they only offer a 108 degree lobe seperation in the profile I want. 240Dur at .050 and 590 lift

Lunati has the same profile with 112 degree lobe seration. My car is a road racer and I do drive it around the back roads. Do i need the wider lobe seperation?
