If you think about the way it is designed, the location of the hottest 
point depends on the design of the head gasket.  If the head gasket has 
most of the flow going up at the rear and just a trickle in the front 
portion, then the hottest point will be at cylinder one.   If there is a 
lot of upward flow near the front and little at the rear, the hottest 
point will be cylinder 4.  If you take water out at the heater port you 
will encourage flow to #4, but #1 will receive less water, so it will be 
hotter.  With a little experimentation, the size of the holes could 
probably be optimized so that 1 and 4 are at the same temperature..  I 
think the stock gaskets cause #4 to be hottest.  I like the way Mordy 
does the holes in his gaskets with big holes at the back.
