If do not value the car & like learning new things , I'd say go for it , but tools are a biggy when it comes to doing any mach. work , then this is big enough job that you should have a teacher/ journeyman/ instructor - a lot of details .
What is wrong with the head , how do you know the head is junk , is it off the car ???
If the head is junk , then your already going to spend at least a few hundred , junk yard head , rebuilt , gasket set , water pump , timing belt ect ,
If your going to spend a few hundred then you want to get some long term use out of it , you may want to have it done ,
Where abouts in Wis. are you ? If it was close enough , then you might get some help , lots of variables .
