spark plugs

I have a 77 F-250 with a 460. The spark plugs get carboned up fairly quick I was told to use a hotter plug Any suggestions?

Maybe. I think I would find out why the carbon. Too rich? Burning oil?

Hotter plug may work but you need to do some troubleshooting to find out why the plugs are carboned up in the first place.
Like V10man said, it could be running rich (dry black carbon) or burning oil (oilly, crusty deposits).
Unless you find out why, then you're only treating the symptoms not curing the problem.
