Ladefoged did a lot of work on labiovelars in West African languages (see "A Phonetic Study of West African Languages" 1968 or Ladefoged & Maddieson "Sounds of the Worlds' Languages") and records that ingressive (or implosive) production of labiovelars in some languages, though I can't recall right now which have it and which don't - I'm pretty sure it glottalic ingressive production occurs in some varieties of Igbo, particularly since one dialect, Owerri (?), IIRC has both voiced and voiceless implosives at labial and alveolar points of articulation.
