I have been working on my problem of the sparkplugs loading up and the effects the shielded leads have on the ignition system.
The standard plugs are over $10 dollars each and you need 8 of them.
They do not self clean and run a every small gap due to the poor spark from shielded leads.
The long manifold on a straight 8 tends to dump a bit of raw fuel on the bottom of the manifold when cold.

I ended up chopping up the old set of HT leads and pieces and made this.
