383 and 440 Super Commando's should have the dual snorkel style.

All others would be a single snorkel. '67's should have the flared cylinder style air snorkels (not the tapered ones).

Not all 4-bbl motors were Super Commando's. What is your exact application? (just saying 4-bbl B-Body is not specific enough)
