That car is so rusty that I would think twice about putting too much effort into it, especially in Northern California where there are still good ones around. I live in the bay area and bought and resold multiple #17 and #22 heads from Pick n Pull in the last few years, so with some effort and luck you can get them for under $200 if you want to do that. They are a bit of work to pull, even after pulling 6 of them it's still a 4 hour job for me to get one off with hand tools.
