Gap = 0.050" according to the service manual for your engine and year make.

Torque = Gut-en-tight (no numerical value given...aka hard snug tight)

THANKS! Any thoughts on what the impact on performance would be if they were at 0.40"?

A couple of things come to mind; hard start, rough idle, or engine hesitation, where not enough voltage needed to be generated to create a strong enough spark for a successful ignition performance.

No guarantee on this assessment as internet troubleshooting can be a rough order of magnitude.

Best on the solution.
