Ah yes, the infamous Chevy 268 Cubic Inch V-8 for the Monza. Definitely a
design nightmare from the mid-70's! Most owners just left that last spark
plug in there and did not change it till it caused a misfire condition...

Most cleaning and repairs are done with the engine in the car.
Usually doesn't come out unless machining is needed. There are
exceptions, of course, where poor design makes routine maintenance
impossible. And even then, they often come up with a workaround.
I am reminded of the Chevy Monza, where it was impossible to change
one of the spark plugs. The repair kit consisted of a hole saw, a
template to show where to put the hole in the inner fender, and a
rubber plug to fill the hole when done.
