440 heads on 413 engine?

["David Whitney" <david.whitney@xxxxxxxxxxxx>]

I know there's interchangeability between 440 and 413 blocks and heads, but
I can't find specifically which, if any, 440 heads I can use on a 1960 413
block.  Can somebody point me to the right reference?  This is not my
project, I'm asking on behalf of the builder.  And yes, it's for an
Imperial.

Thanks,
