Coil Packs
I just run gmpp plugs with stock heat shields on my build. Fancy granatelli wires burnt up on my car but was not using stock heat shields at the time.
If plugs are saturated seems to me you have a fuel /tuning problem. Not sure what injectors you are running,what fuel pressure and what tuning.But that is far more likely or possibly bad o2s.
Not likley to be fouling out iridiums unless you are way way up there in cold range like tr8ix and trying to run 5psi or something.
Also you will see many very very fast cars with stock coils.And you can turn up dwell on stock coils if you have hptuners.
I would think guys running past 20psi might benefit mabye from the more powerful truck coils.
Sims are only so it don't throw codes from not running the back o2s.
So if fouling plugs big time with fuel would be pig rich and likely something is set very wrong in the tuning.

also if you have a stock fuel rail, the inlet pipe will need to be bent slightly, and the fuel evap solenoid will need to be relocated
