I can't say anything about the performance. But if you just go by the numbers, it "seems" worth it to me. A 35 mm carb has @961.6 square MM of area. if they were bored to 36.5 the number climbs to 1045.8 square MM. If my math is right you gained almost 9% in area of the carb bore. On paper it looks like enough of an increase to justify the expense. As far as real world application of it, who knows. I am just an idiot with a calculator. But when I break things down like that, they just make more sense to me.

Evil I don't know if anyone does it anymore but the carb can be bored up into the body. If you look at it when done it would look egg shaped. That way you get more bore but keep the original slide.
