the main problem you might face with the tighter settings is that the valve doesnt seat properly with the weaker K24 springs, equalling loss in power

Correction - K20 and AUDM K24A3 spec are the same... lol i was looking at the USDM K24A3 spec...

K20 spec:
Intake: 0.21-0.25 mm
Exhaust: 0.25-0.29 mm

K24 spec:
Intake: 0.21-0.25 mm
Exhaust: 0.25-0.29 mm
Why don't you install some ITR springs while you've got everything pulled apart Justin.
