This is the tried and true method of grounding:

Negative Battery Terminal to both frame and engine (block or cylinder head)
Opposite Side Cylinder Head to frame
Intake Manifold to firewall
Transmission to Frame (because ground current will go through the transmission bearings)
Gas tank and fuel inlet to frame
MSD boxes and under dash wiring should have a dedicated ground
