Deburring process

When you're deburring the water jackets is it still for the same benefit of increased flow? Then as well with the sharp outside edges, is there any further benefit than just limiting what you may cut yourself on?

Hello Trenton, i guess that depends on the restriction, but NO there is not a flow or cooling benefit. just a tidy job where bits of metal or alloy won't hurt you or float through the cooling system,
