Spread for head (4)
I believe the answer is:
pate
I believe this clue is a double definition.
'spread' is the first definition.
(pate is a kind of spread)
'head' is the second definition.
(thesaurus)
'for' is the link.
(Other definitions for pate that I've seen before include "Crown of the head" , "Posh 8" , "Tape around tasty meat paste" , "Savoury spread" , "crumpet" .)
