AFAIK they're the same as the 100s regata and the 2 litre 131 we got in OZ, 43.5mm and 36mm.

Thought 1600 twin cam had bigger inlet valves then a 2000tc 131?

Hi,
that's correct valve in 43.5mm and out 36.4 mm.
and attention valve adjustment measurement are in 0.35 mm out 0,45 mm not like 131 Racing/Sport!

The series 2 and 3 twincams in the 131 superbravas in OZ had 43.5mm inlets, the same as the 100s regata 1600 twincam, which AFAIK is the same head as the 130TC.
