Look at the schematics for grounds in the service manual. There are a few on the back of the heads and many more throughout the engine bay, to many to list.

I have a swapped car but the only grounds from the chassis to the engine for me are one 4ga ground on the front pass side of the engine, one small ground from the wiring harness that attaches to the pass rear head, and one 4ga on the driver back head. Not sure if that helps but that is what I have.

Just make sure you get the ones on the heads hooked up right...I didn't have the ones on my driver's side head bolted all the way down and it was making my car do some crazy ****.

There's a thread in the Stereo/Electronics section that has a ground list.
