Milky Oil - Need Help

Engine had a bad oil leak from the valve covers so I swapped those gaskets, as well as the intake gaskets at the same time. Put new oil in it during that time as well. Got it fired back up last night for about 15 minutes and everything was good while timing it after installing a new HEI.

This morning went back out and fired it up again and it was an instant smoke show from the exhaust, radiator was empty, oil was a milkshake.

Any guesses? Never had any issues before the tear down except for the leaking oil.
