Correct Plugs for GT40P???

Hello,

So I pulled my 351 this winter and had it rebuilt. I followed the recommendations from many of you and went as follows:

351 PCM RH (.30 over)
Cam Research Water Ski Cam
GT40P Heads (pulled from 97 Explorer refurbished and custom valve job, new springs)
Edelbrock Performer Intake
Holley Marine Avenger 4 bbl
D.U.I Electronic Ignition

My question is which spark plug to utilize in the new heads?

I can go with the standard/performance plug for the 97 Explorer or mimic what PCM used on the later engines with the GT40P's but wanted to know if any of you have any suggestions/experience?????

Thanks

Keno,

Thanks for the follow up. By standard/performance I meant essentially what you listed.

The standard Autolite/Motorcraft/NGK?

or

The Iridium/Platinum/Golden laced laser cut carbon copper titanium blah blah blah........... load of marketing crap of the week buzz word.

I just didn't know if anyone had found a better than most combination.

Thanks
