Sparkplug gap?

[danmc77]

Getting ready to install new Champion plugs in my Eddy heads after a top-end rebuild. How do I know what gap I need for the plugs? It's a 440 w/ 10.2:1 CR, Mallory 6A, and Unilite distributor. ERC12YC plug.

Thanks.

Start out at 45 thousands and go from there.Engines tend to take more/less
depending on setup,hard to determine without probably running at the strip
to see the difference.I run my cars no less than 45 with the MSD.
