5.0 Plug P/N's for stock and various head combos

[DFG_magic]

I have a 95gt stock headed with a Powedyne and 6lbs of boost. Autozone gave me asf42c plugs. I didnt see those listed earlier in the post. What should I run and at what gap with boost. They say to tighten up the gap when running boost. Thanks.

Ahh, I would rarely recommend taking their advice. Pull those out and slap some Autolite 24's or 23's in there. Gap them at .044 and you should be right where you want to be. The 42c is a hot plug and I only suggest Motorcraft plugs on bone stock setups and some FRPP head setups. Maybe the 32c in a Motorcraft.
