Paul,
Are you interested in "correct" relative to original?
I have never had a problem following the factory wiring - with the correct cable/leads and clean connections.
Nonetheless, on my 1954 6v Suburban, I run a long 00 (2/0) gauge cable from battery to starter bolt. Also as described by Jerry, I run a frame to clutch housing ground strap, as originally done by GM.
Actually, in 1954, GM suggested a ground strap on both sides of the frame to the clutch-housing, and one ground strap from the coil-side of the head head to the firewall (with a radio).
