If you have a projected nose,
should you worry at all about the longer ground strap getting too hot at high load?

Along with longer ground strap changes, what about multiple ground strap changes? Autolite view:

I confess to spending way to much time
indexing spark plugs,
cutting off with a Dremel tool the particular ground straps of Bosch +4 that ended up nearest the exhaust valve off, making them into custom Bosch+3.

I now like NGK Iridium projected nose plugs where great factory quality control and longer life justifies higher cost.

I like the no longer sold
KAL Equip 2969 spark plug analyzer
with its Peak KV, Burn KV and burn time readings,
although it does not work well with “wasted spark” type ignition systems.
I eventually bought another used KAL Equip 2969 unit for $70
to have two so as to more easily compare “known good” cylinder to “suspect” cylinder at the same instant in time.

If you “on purpose” create an air leak at a cylinder for lean a/f
or add propane to a cylinder to create richer a/f
the KAL 2969 is sensitive enough with its 3 readouts to show a/f differences.
