Default Identify Camshafts

Can anyone advise how I identify the cams fitted to my engine?

As an example, the Part Numbers I can see on one camshaft are:
  • L3IN
  • A9

What type of valve clearance adjusting shims are fitted ?
Over bucket/under bucket/under bucket top hat ?

Markings on the cam are similar to STi Version 2 RA and shims would be under bucket top hat shims ( far left in the picture below )

Much appreciated - Confirms what I was told

I don’t suppose you know the duration and lift profiles of these? I have been told that they are the best oe Cams for my car which is a gravel spec. Rally Car running a 34mm Restrictor.
