Jap was fine for our grandfathers and perhaps our fathers but is regarded as very poor form today. JAP is OK when talking about the British motor.
Shims under bucket has been pretty fair for big performance in line fours that reach stupid high rpms. It's a very stout way to maintain valve clearances under extreme conditions. I don't see any manufactures changing that. Pain in the keister, but typically actual adjustments seem to be few and far between so a bit of sugar on the bitter pill.
