Can't you just do as you say with grounding each head to the block and then grounding the block on both sides to the chassis instead of running a whole other cable to the negative side of the battery?
Learning curve here as well.
Me and electricity is like a kite and Ben Franklin. I guess he grounded himself as well back then. LOL.
