Does anyone know if a cylinder head from a 62-65 HD truck will work on a 60 Impala 348?

I noticed that you said a cylinder head rather than heads. As Cecil said they will fit, but I just thought I'd add that if you use the #333 truck heads you should use them on both sides of the engine. They are slightly different from other 348-409 heads because they have a bigger combustion chamber, so the compression will drop about a half of a point when you use the truck heads. You'd have to use them on both sides to get an even compression ratio.
