Moisture between head and exhaust manifold

Moisture between head and exhaust manifold
I recently replaced the head gaskets, timing chain, intake gasket, etc... , and also had the heads rebuilt on a 71 455 and I'm still trying to work the bugs out. I noticed between the head and the exhaust manifold there always seems to be moisture between the too and when it warms up it smokes. This is only on the drivers side right above the dipstick. I'm assuming its oil but I have no idea where it comes from or what causes it. Hopefully nothing serious but this has been a learning curve for me so a mistake on my part is possible.

Should have added that in, I originally thought it was oil from the valve cover because it was leaking slightly right above the moisture areas so I went ahead and put a new one on and made sure it sealed up good with no leaks now, however the smoking and wetness is still there. Ill see if I can figure out if its oil or coolant.

The five exhaust bolts on an Olds should not reach water, unless there is crack or some other condition present. I might suggest the addition of a dye and uv light to narrow it down after you've done what is already suggested.

I have seen this a little bit on mine, I chalked it up to the diff in material between the aluminum head and the different metal of the manifold, they cool and heat at different rates. Obviously if you have stock iron this would not apply. Mine is plain old condensation- I used toilet paper to see the color of the "water".
