Cool My turnkey is getting the same motor, with Holley throttle body EFI
I assume that it will be delivered with the motorcra* (or similar) plugs, which is fine for break-in, but I will go with a splitfire or other dual spark plug, when change time comes, BECAUSE I will have the (awesome) MSD ignition, with the MSD Blaster high output coil.

The point is, your coil, etc... are mostly what should determine if it's worth the money for the higher end plugs...standard type ignition/coil, use the motorcra* plugs...
the MSD can literally jump several inches of gap, I have seen them demo'd...and they can do this at over 10,000 RPM! So it can really use a splitfire/etc.. and a MUCH larger than standard gap. This gets a lot more fire into those monster lungs
