Valve clearance check

Since the Toyota VVT-i engines are prone in valve seat recession when running on LPG, I decided to take a reading of the valve clearance (even after being told that this would not be a problem by the guys at Front Fuels).
This is the valve clearance readings that I got:

Intake valves: 0.15-0.25mm, reading was 0.20mm
Exhaust valves: 0.25-0.35mm, reading was 0.30mm

The engine had been stopped for some time but it was not "completely" cold, so the values could be somewhat bigger than expect at cold engine temperatures.
This reading was taken at 131357km (2500km on LPG)
