$2000 budget to start

[Dad's72]

Okay, my truck hasn't run in probably 20 years. I did get it started up a couple years back but he carb got gunked up. What would be the smartest way to spend $2000 on it? I am not worried about anything cosmetic at this point. Strictly just to get it driving. It was my father's so I know it is all original down to the carb. No shady work has ever been done to it. So that is good I guess.
I found an old work ticket in the truck and it said something along the lines that there was some valve adjustments done to it before it sat. So I am thinking that the heads may need to be rebuilt on it. There is a machine shop here that will do them for just over a $125 a side.

What would some of y'all do that have done this before?

I'm trying to get a game plan together for such a small budget. I can probably get a more made before too long, but that is all I have right now. Next year will be better since a small loan I have will be paid off at the end of this year and my youngest will be out of day care. That together will free up about $1100 a month.
