Porsche Crest 930 EFI Spark Plugs

I am looking for input on spark plug choice for my 930 EFI conversion. I know that the W3DPO plugs are "cold" and the factory did this for a reason. But, are they necessary for electronic fuel injection?

I will be running a 3.2 Motronic ECU with twin plugs being fired from a JB Racing distributor. The fuel pressure regulator is a Protomotive rising rate unit. My injectors are Bosch 944T (as designed by Todd Knighton of Protomotive).

I am looking for an educated, first hand opinion here. Please, no shoot from the hip suggestions.

Thank you,
