grounding heads

ok;;i've been on here looking at all fourms on grounding..here is how i want to do mine and need to know if it will work this way ok..
[1] 4ga wire going across from head to head at rear of engine;
[2] 4ga wire from one head down to engine block[front of engine pass side]
[3] 4ga wire from eng block[from same location on block as[2]wire to chassis
[4] 8ga wire from - on coil to engine block[drivers side]
[5] battery in rear of car[door slammer]ground from batt. to chassis at rear
of car

just make it simple ground each head to the frame all you need 2 wires your done

 

IMO
Since the goal is to complete the circuit, I ran mine from coil to cylinder head. The head is obviously connected to the spark plug and that completes the circuit.

 

both of mine are grounded to the same place on the frame as the coil

 

The MSD directions tell you to ground the coil to both heads.

The spark plug isn't connected to the frame.

 

so will my way i'm wanting to do work then?i have the mallory super mag111

 

I am only familiar with SM II, III & IV's.
I've had more motors work without any "extra" grounding than those that needed it. But I also wish I had back those runs that I "wasted" because of a poor ground. Its cheap and easy to do the extra grounding.
If I were you I would run a wire from the coil directly to each head and be done. I have a male/female spade quick connection so when coil or heads get removed its quick and easy.

 

Coil to heads per MSD instructions. And definitely use a ground wire from your battery forward to a ground block and use ground wires from each circuit to the ground block, copper is a much better conductor than chrome-moly etc. The only reason the frame of a car was ever used for a ground path was to save money.
