Hi,
What are the best spark plugs for a 1969 Toronado?
Any opinions or comments please.
Regards. Neil RG Fudge

My opinion based on experiences buying exotic plugs is that anything more than stock replacements are a waste of money that could better be spent on cold beer. Therefore I just go to NAPA and they look it up in their book and I take what they give me.

Just regular copper. Delco, Autolite, Champion, NGK, they will all work just fine

I was a big fan of Autolite...until they sent production to China. Now they can K my A.
NGK seems a reasonable plug. They're making stuff that shows up in AC-Delco boxes.
Champion had the most brittle porcelain in the industry thirty years ago when I swore I'd never buy another one. Soft, fast-wearing electrodes, too. Total junk.

Along the same line what is the best way to remove plugs that have rust on the exposed threads? My gf inherited a 66 and the exposed threads are rusted. Am thinking pb blaster soaking for a fee days? They look like they have been there forever. Perhaps leave it till there is a problem? Just thinking about being proactive here.

There can be NO exposed threads if the correct plugs were installed previously. If the correct plugs were not installed, it would be more likely that the plug would extend too far into the combustion chamber than exposed threads would be visible.
The plugs are sealed with either a gasket or a taper, either way the sealing surface will completely gas-tight. Spraying penetrating oil will do absolutely no good whatsoever--the oil cannot possibly get to the threads, because of the gas-tight seal.
Short story: if there's any foreign matter around the spark plugs, blow it away with compressed air. Put a socket on those plugs and spin 'em out. This isn't a Ford Modular engine that has the design defect where the plugs and cylinder heads are routinely ruined.
