I note that everyone now seems to adopt a greater clearance than both Austins originally and the revered special book writer Williams recommended. Presumably modern exh valves are of modern material which expands more than XB and earlier steels. (Unless valves are of two piece welded construction)
Valve clearances for "modern" cars are very different because these have opening and closing ramps to reduce noise, impact and sensitivity to wear.
