Default Weird antifreeze problem

I'm loosing antifreeze everytime I drive the car then let it cool.Have to put in about 1/2 quart everytime into the radiator.It's the same if I drive 30 minutes or 2 hours.I even drove 130 miles did 20 passes and drove home and only took a 1/2 quart
So far I pressure checked the system hot and cold with no results.Even replaced the radiator cap figuring the the fluid was not sucking out of the resivor.Been doing this for awhile now.I even changed the Heads to another set with new gaskets with no help.

Any idea's???

Has a little smoke at idle,but no sweet smell.More of a rich smell from no Cats and a lopey Cam.

Well,I pulled the plugs and found the problem.Cylinder #3 was burning antifreeze Started to pull the heads and saw antifreeze on the intake valve Looks like the port is leaking somewhere
I'm going to find exactly where it is leaking then hopefully have it welded.

Hey make sure that the gasket looks good, it could have been leaking into cylinder...then resting in the intake valve when you shut it off..? hope no cracks...sucks.huh
