interesting crey... I installed new heads/intake/carb... but for grins and giggles, i held my hand up to the exhaust, and it felt a little "humid"... wonder if that's anything significant?

 

there is a allen screw in the front of my block for bleeding. open this when cold and wait til water comes out and close it again
do that first of all.

i'll get you a picture ...

 

it's on the thermostat housing

I would not be too concerned unless your exhaust is a white cloud. When you burn fuel you have some byproducts like carbon monoxide and hydrocarbons. Another byproduct is water. If you see white smoke out the exhaust when the engine is warm, you probably have a coolant burning issue. In some cases, you can see the coolant drip out the tail pipe, but you will get some water drip from the exhaust even when things are running right.
