What are the most common cylinder head valve size and camshaft combination with the 32, 37, 45hp?. I notice that nobody talks about specific camshaft sizes to achieve those Hp.

Since the aircraft version of these engines are limited to low RPM operation compared to their automotive use, bigger valves and hotter cams do not offer any benefit. Stock size valves and a stock cam work best, we don't talk about it because there's not much to discuss. The different horsepower engines differ in displacement.
