Hello- Welcome to FTE! Check out the list of tech forums we have on FTE. There is a wealth of information and expertise here to help you. There are a number of links in my sig below to help you also. Have fun! 
Most of the time it is a bad head gasket.
Engine Identification (rev):
======================
351C/M/400 335 series: 8 bolts in rectangular valve covers. Timing chain housing is part of block. Thermostat housing on block. Exhaust bolt holes diagonal.
351M/400 335 series: intake is 12.7" wide the 351C is narrow.
351W/302/5.0L 6 bolts on trapezoidal valve covers. Thermostat housing on intake. Exhaust bolt holes horizontal.
429/460 385 series: 7 bolts in rectangular valve cover
352/360/390/427/428 FE series: Intake goes under valve covers.
-There are other indicators but these are enough to distinguish engine families.

As Eric said, It is usually a head gasket, but there are other things too such as leaking intake gaskets at the water ports to the heads (but they usually leak externally too), cracked head or block. The best thing to do is to use a pressure tester on the cooling system to see where the leak is.
