The size of the valves per-se is not the issue, it's the amount of material left between them in the head. the extra heat of the charged burn can lead to heads cracking.
I'm doing the harewood championship in 2013, so I'll be there lots. Might do an Olivers Mount too.

37mm inlets and 31mm exhausts are what I run,
on the 7 port heads the valves a bit further apart so your in a better position to run valves of this size.
