Heavy Head is a skiing term for dropping your head like it weighs a hundred pounds after landing a steezy rail / jump.

It goes right a long with the afterbang in enhancing the overall steezyness of the trick itself.
"Man you if you had added some heavy head to that afterbang, it would have been a legit landing."

Heavy head is just what adds that extra something to the jib.
