A standard socket is fine, you’ll need a short extension to clear the pulley. A deep dish socket is still usually a little short of clearing and the pulley without an extension.

I’ve gone back and forth on plug manufacturers, if those are the right heat range for your set up I’m sure they’ll be fine.

I removed all the spark plugs and I couldn't rotate the crank pulley by hand...

UPDATE: So, I just went to harbor freight and bought some sockets. Using the breaker bar, I was able to rotate the crank without using the jack lever as a moment arm. So, the engine is good.

The question now is, what stopped the car?
