jegs? on ford heads

i cant find their email, but the price that they list for their aluminem heads is that for each head or a set? because i see under other head sections it says the same price range but each in parenthesis so i know its for 1 head, but unsure for the FMS heads.
 
if the price is around 500 bucks, its for one head, if its for a over 1000 its for a pair, thats how it usually works in most cases. if its the gt40 turbo swirl heads, those are about 500 each
