1968 Barracuda Notch 340

Would adding material to the top edge on the inside radius to make them "more" even help?
Is the bumper semantical? could you flip the tips if so?? IDK
So, bumper is nowhere near symmetrical. I cut off ends, reduced length by .5", mocked back on, now deciding on the best cut to bring the return end topside closer. The problem is, the the whole corner of the bumper is essentially a large round cup or hemisphere, so this will involve mitigating the compound curvature.
