RW> Never saw one open, so I can't say that they do or don't have rockers.
 
He didn't remove the covers as that would have been a gigantic waste of
time.  Atop each cover are access panels revealing the ends of the cable
and the plugs themselves.
 
RW> Buick and Cadilac did that. The newer engines don't have distributors.
 
That, I didn't know.
 
RW> They have a crankshaft sensor on the V8s that tells the computer to fire
RW> one coil for each cylinder. The coils are mounted on the valve covers
RW> over each spark plug (spark plug wires are 8" max). The V6s have a
RW> two-pack coil that fires more than one cylinder.
 
My engine has a coil for each bank and they are mounted forward of the
heads. I haven't looked at them lately, but they each are about the same
size as my fist.  I really don't know a whole lot about this setup.
 
RW> Yeah, but the 5.4L V8 must be the one that the spark plug shield stays in
RW> the cylinder...
 
Probably so.  I remember the first time I popped the hood on my car.  I
couldn't see much of the engine because of the enormity of plastic covering
atop it.  I had a heck of a time finding the transmission dipstick.  It was
a couple of inches forward of the cowl on the right bank and tiny!
