The process of installing seats in the head reduces the strength between the valves quite a bit, making the possibility of cracking between the seats much higher, so the size becomes more of a compromise of performance vs reliability. I suspect that is the reason John Parker is using 36mm valves when using inserts in his ported road heads.
