well if you have the heads flattened by a machine shop and since they're off, you might as well go for a valve job, then I'd suspect you to spend about $200-250 for everything. Go to autozone and get Fel-pro replacement head gaskets, they're under $20 apiece and are good gaskets (unless you plan on a big blower in the future.
They will have the rest of the gaskets you need too.
Having the heads off is a great time to port them, if you can do it yourself then its really worth it. Have the machine shop inspect the valve guides as well.
dont feel bad about having to drive a mini van. I'm away at college with only my stang, and I just snapped my clutch cable last night. I have hardly any tools here either. I guess I shouldnt be comparing the repair of a clutch cable to a head gasket, but atleast you have a backup vehicle
