vortec head spark plug gap

[jabo]

I have a set of v8 vortec heads on my 80 malibu. I was wondering what should i gap the plugs at, they are champion RS14YC6. Thanks!

I believe the factory called for .045. If you have the right plugs, the side electrode should be very close to flat across the center electrode at the proper gap. Not angled open or closed.

On the MFI Vortec engine they're set @.060" but, for a Carbed setup .045" should be good.
