Your DIY Looks very good. Remember the short side radius, its the ONLY place besides basic port matching that does anything to speak of. Smooth it out, increase the radius as much as possible. For extra but almost nothing, swirl polish the intakes, back cut the intakes, exhaust, radius the exhaust valve edge and finally incut the exhaust face. I suspect that most of this valve work is next to less than 1/2 percent total, but thats what the racers do.
