This has always been misunderstood.

This is how it works in plain English.

The negative battery cable goes to the engine block. That makes the engine the main ground. The system grounds from the engine harness are bolted to the motor on the back of the passenger side head. These can be bolted to the motor ANYWHERE because the entire engine is metal and aluminum. Both great conductors.

The best place IMO are the 2 rear passenger intake bolts. This for easy access and inspection. it’s cut and dry.

From there, run a ground strap from the driver side rear intake bolt to the firewall.
This grounds the body of the car. And that is all that is needed.

Don’t over complicate.
It’s plain and simple.
