Default Toda B valve clearances, do any of you have issues?

I'm running JDM ITR pistons in my GSR block with Toda Spec B pistons and a 2 layer mugen head gasket. I talked to a local tuner and he told me that i should be running aftermarket pistons with deeper valve reliefs because he is afraid that my valves might smack my pistons, causing death to my motor. I didn't really know JDM ITR pistons were big enough to give me valve clearance issues, what do you guys think?

How much lift are those cams?

edit: Does anyone know if the JDM ITR pistons have the same valve reliefs as the USDM ITR pistons?
