Try it and see The starter has the biggest current draw so providing the easiest path for the current makes a lot of sense to me I think iron conducts electricity better than aluminum

I see several errors on his information, gold is the best conductor, hence the gold plating of high end connectors for the high end devices, especially in the aircraft and space programs Basic electricity classes cover the different metals used in the power and entertainment industry, the power company converter to aluminum lines to save money even though they have to have to use a bigger line size compared to copper lines.

We do it in the racecars. Both aluminum blocks but we have even seen excessive corrosion on the outside if they are not grounded.

I need to correct the above, Silver is best, but it tarnishes, where gold does not why gold is favored. For example, in FE racecars, the wiring is mainly pure silver.

Is this the series that replaced Formula one? If so I saw part of a race on T.V. of those cars and watching them accelerate away from a corner was not very exciding with out any exhaust note of the motor accelerating , no tire squealing noise or anything else

The kids won't know any better. I believe the hidden OP's original question, I can't see how any electrolysis he thinks he spotted has anything to do with grounding on the head, but that is only my guess.

There is an Anode in a radiator cap for this.

Thanks for all of the replies, I think I will continue to ground to the head. Good to go. But I'd still think of putting an anode in some where. They also make drain plug replacements that screw in the radiator.

Grounding both heads will help with electrolysis when it's running, you have a basic battery exchanging ions through the coolant due to the dissimilar metals in the heads and block. Adding an easier "path" for the electrons flow will help reduce the electrolysis effect on the head studs,head gasket fire rings etc and technically,you get a better spark. I run an earth from the batteries in the trunk to the block, the starter motor turns the engine over a lot easier. Sure it adds weight but your ignition system will thank you. EDIT: Some coolants also have corrosion inhibitors which will help also but not all drag strips like you to run anti freeze / summer coolant

Grounding to the head is no problem, especially if you're also grounding to the starter or to the block next to the starter. What are you using for coolant? Distilled water might help if you are using tap water. Some sort of additive is also a good idea such as water wetter or something like that. i have read in a few places not to use distilled water. I'm not a chemist but it was said that distilled water has been stripped of all minerals and when you put it in you motor it will eat the metals to try and balance itself back out. it said use softened water whatever that is.
