HEAD GASKET

1998 Ford Escort

Engine Cooling problem
1998 Ford Escort 4 cyl Two Wheel Drive Automatic 146000 miles

I have 1998 ford escort 4 cylinder sigle overhead cam.
The resevoir for the radiator is overflowing. I changed the therostat thinking it was stuck open.
A friend is telling me it is the head gasket or heads.
I do not have money to put it in the shop and want to repair it myself. Can you let me know what else it can be and also what I have to go through to remove the head to check the Gasket?

Thanks
