Other spark plugs necessary for 911 2.2 T with S pistons?

[Heinz911]

I have now reached the point, 1000Km after my rebuild, to check the valve clearances and the cylinder head torque. when I'm in there I would also like to change the spark plugs. I have installed S pistons in my engine that result in a higher compression ratio. Does this setup require the standard T plugs (Bosch WR5DC) or should I use the ones for the E and S (Bosch W5DPO)?

Thanks for your response!
