Thanks OMT. From someone of your standing that makes me feel pretty good for an amatur. I got a lot of helpful ideas from folks on this forum.

Honest dad, that 455 on the side of the block is a serial number

OK stupid question, obviously the coolant flow is something I have not paid much attention to...

Is the theory here that as the water is coming up thru the block and heads it is better to have it going out thru all 4 "corners" of the heads rather than only at the front?

After discussing this at length with other members, my take is this. The water gets a little stagnant at the rear of the cylynder heads do to the tendancy of the water to take the path of least resistance. It tends to favor the holes in the block closer to the front and not force a great amount to the back of the block and heads. Thus the hotter running rearmost cylinders, which seems to be a proven fact in pontiacs. If you add the hoses, it draws more water accross the rear cylinders and creates more flow in the back of the heads which in turn provides better cooling of these areas.
