Question on Spark Pugs go with a colder or hotter plug ??

[Nassau1969]

I have a 440 with 10:5:1 with Edelbrock heads very mild cam Edelbrock carb and intake, stock exhaust. I use Champion plugs that they say to use with the heads. I have about 3000 miles on the motor. I seem to foul out plugs very often. It will run awesome for a few weeks then if you start it and get a miss start they sometimes foul out. Or after the engine is hot and you get a miss start they fouled out. The miss starts don't happen often.  Other than that it would run perfect and performance perfect. Anyone out there with advise. Maybe a hotter plug or colder plug.

Use an NGK BCP-6ES and your fouling issues will be over
