Spark Plug Recomendations

[Cudajason]

Hey guys, I have new spark plug wires and wire looms on the way.

I figured I should also replace the spark plugs while I am at it.  I figure with the new manifolds on, it should be a easy task!

Any suggestions on what sparkplugs to use.

360 small block, old Edelbrock Torker cam, Holley 750 vac secondary carb siting on a Edelbrock perform RPM intake.  Around 8.5 :1 compression.

FWIW I've been using NGK GR4's since 2011. It's a 318, bored 40 over, 340 cam, 340 exhaust manifold, Edelbrock LD4B intake, Holly 600 cfm, guessing around 9:1 compression.

I use Champion RN12YC or Autolite
Never liked NGK they foul too easily & never fire again
