Ones that spark.

How about some more info?

Compression ratio, forced induction or not, cam size, nitrous or not, altitude (if it's not in the "norm"), gas you're using, etc.

I dont know how much reach your heads require so I'm basing plugs off what I ran. With that super low compression and fact you have aluminum heads, you have no choice but to run the hottest plug you can get per manufacturer for your heads....why did you go sooo low in compression with aluminum heads? even with a super tight cam with factory spec duration your losing out on alot of power due to heat disappaction and not being able to keep the chamber "hot enough" so for practical purposes your essentially running a 8.3:1 compression.

Not sure if your really going to be happy, since it's surely not going to be making nearly the power it could've with a better combination.
