Cross section of 16v head

[calimus at techography.net (Calimus)]

Does anyone know of an image of a cross section of a 16v head that
showes the water jackets?

Reason I ask is that back in April, my rocco start what appeared to be
overheating via the water temp gage.  Problem was, the oil temp gage
says everything is normal as does a simple grab the hose heat check and
a few other put your hand there tests.

So far, I've replaced the following, temp sensor, temp gage, water pump,
flushed radiator, checked hoses for rot.  I've also done compression
checks to make sure the head gasket is still intact, everything checks
good.  No water on the oil or oil in the water, no white steam from
exhaust either.

I just put the car back together Friday and tested it Saturday and guess
what, same problem persists.  At this point I think I have something
blocking a water pathway in the head right by where the water temp
sensor is.  Obviously I'm not going to get this blockage to go anywhere
by beating the snot outt the car as that has already failed to due to
the trick.  So I wanted to try and get an idea for how the water jackets
were layed out so that maybe I can run something in there and break it
up or loose or something.  For all I know it could be a scale from the
block/head that flaked off.  So, anyone know where I can find a cross
section or something?
