How do you know when you have "S" cams?

[Mark Kingsbury <cubrr@domain.elided>]

Hey folks,

    I just got a set of GTV-6 ported/polished heads with oversized
valves for birthday! (Thanks Dear) They are supposed to have "S" cams in
them and I was wondering was sort of markings/numbers would identify
these as "S" cams?

Grazie,
