Will this work for HEI ignition module heat sink compound ? It is both thermally and electrically conductive so I know I can't go overdo it due to potential arcing.
It looks more for IC’s, but I’d say it would work.

If you plan to use heat sink paste, and want to get it sooner I would just go to your local computer/electronic store and buy a small tube of Arctic Silver 5 or MX-2 because of the metals used.

This is fairly reasonable in price, and it works. Make sure it says heat sink or thermal paste on the package. You want it to transfer heat. Also, the Super Lube is dielectric, so it won't be conductive. Win-win.

Don't bother using plain dielectric grease on HEI modules. It needs to be heat transferrable. Plain old dielectric grease isn't designed for that.

$6 and change from Amazon.
