As for letter-spacing of small caps in headings per se, Jan Tschichold
wrote in the Penguin Composition Rules (1947):
`Use small capitals for running headlines and in contents pages. They
must always be slightly letter-spaced to make words legible.'
If you check a Penguin published in the last fifty years you will find
that this rule is followed. It is also standard practice for zillions
of other reputable publishers. I pulled down books from my shelf
published by Cambridge UP, Oxford UP, and Dover. All three are
typeset in Baskerville and all three have letter-spaced small caps
