Spinning the stock pump to hard?
A friend of mine has had this problem with his mustang. He is running a tiny water pump pulley and some crank pulley that looks like a spare tire. It had quit pushin water because it got low enough to give it room in the radiator. he tried some new shift points the other day and it filled the overflow up again.

the pulleys are march serpentine standard size. the pump is a edelbrock. the radiator is an aluminum howe i believe its 3x26x18. i have not had it pressure tested. i figured the temps are good 180-200, so would'nt that rule out the head gaskets? running a 16# cap and i have a 22# i can try. no shroud, electric fan.

From what you are saying I would believe its a cap
issue... your not running hot but the cap is seeing
too much pressure or its just blowing off early
EDIT
Also you do know there are 2 style caps 1 for a recovery
system and 1 for a over flow.... make sure which you
have.... hold the cap in the up right position and
if the metal disc at the bottom is danging down that
is for a recovery system the other one the disc wont
dangle down... also make sure the lower seat in the
filler neck isnt dented
I didn't know that there were two different type's of caps, wonder which one I have. 
it's ok to butt heads, just don't do it with a butthead

160 too cool (IMO) A stat will not cause an engien to heat. A coolant recovery system the overflow tube must reach to the bottom of the overflow tank or the coolant cannot be syphoned back into the radiator on cooldown. The over flow recovery tank must also be vented or the coolant cannot even enter the tank. There are over flow tanks that are just that - over flow tanks- that are not designed to return the coolant to the system.
