i am not up much on the small blocks, but there shouldn't be much difference between
the 66 and the 68 289 heads. as far as rockers they should work just fine.
the differences were more small changes in runners and comb. chambers
from year to year. generally 289, 302 heads in any of the 60's years, should interchange.

NAPA water pumps are pretty much 'standard', not high flow. I've used them on 289's and never had a problem in that regard.
Did you have an overheating problem before you rebuilt the engine?
Same block?
Same heads?
Same radiator?

I think that it is possible to put head gaskets on backwards, blocking off a water passage. Been there, done that, go the T-shirt. ;-)

Silly question, but did you verify that the fan is installed correctly? Fan spacer places it relatively close to the radiator? Any fan shroud?

heads

Neil what it should have said flush out eng and heads check heads gaskets they are ok Their is a fan shroud every thing looks good Does any one thing that this is the nature of the beast? Do you think i should start pulling the heads off and start going thru the eng again to see if there is something wrong

My first thought would be Scott's (CougarCJ) idea of a headgasket improperly installed. Next would be the heads. SOMETHING is impeding the waterflow/cooling.

PS: Am I going to have to send Rob there to assist you? ;-)

Heads

Neil I live in the Milk And Dairy State Wisconsin Would you suggest to pull the heads and start from their just looking for something?

Before you pull the heads remove both large radiator hoses, remove the thermostat, secure a garden hose into the thermostat housing, and turn on the hose. Does the water seem be flowing as it should out the bottom hose?

Good idea. It just seems to be flowage restriction- either in the heads, block, or radiator (which is new??). Although, I've seen/heard of NEW radiators having blockage.
