[Healeys] running in continued

The necessity for de-coking has increased slightly. It occurs mainly in high
mile engines where oil change recommendations have been stretched/ignored. In
cars that have been maintained it really isn't much of an issue.  In 2+ years
as a service manager of a large dealership where most of the cars were GDI I
can't think of a single time we pulled a head just for de-coking.
There are also chemical treatments that will remove deposits off the valves on
GDI engines eliminating the need to pull the head.
