1985 jeep cherokee overheating always?

[shaynakaderr]

my 1985 jeep cherokee is always overheating. we took it to a mechanic (im not sure he was the brightest or most knowledgeable) but he claims he thought it might be a blown head. he checked the oil dip stick, no milky or white residue. he then checked if there was oil in the radiator, that was also a no. then i asked if he did a compression check he says he might have, and he thinks it came back ok... so im really confused? could it be a blown head? or something else. it just always overheats! what should i look at next? the fans?
