Jim's post makes a lot of sense. The 215s and of course the early Rovers were
some of the first mass produced engines with aluminum heads, today there are a
"ton" of aluminum head cars. It stands to reason the plug manufacutures have
compensated over the years for the increased numbers of these heads.
