So what is the temp. difference, in round numbers? I'm curious too... I would think the head temps would be higher than lower down in the block; most of the heat goes out through the head; that's where combustion is of course but the expanded gases down in the falling cylinder have the heat sucked out. Water flow is suckier in the head too. You might have a hot spot, normal or otherwise. All I know is, temp. distribution in a cylinder head is complicated :-) _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
