Default ohhh please not again (head gasket)

Started my car up 2 days ago after i finished my head gasket swap and i let it idle for 10-15 min while i bled the cooling system. Everything seemed good to go. Then yesterday i decided to check my oil real quick and it looked like a milk shake! I dont understand how this could happen, i just put in fresh felpro 1074s, and used arp head bolts torqued to 75ft lbs in three steps. I am going to try and change my oil tommorow and see what happens but i am really hoping its not the gasket again. Otherwise, i will have to take it to the shop to have it done becuase im not going to do this a third time. I have always run synthetic in my car, but if i do 1 or 2 oil changes just to clean the motor out will i be okay to use conventional? Sythetic is awfully expensive just to clean the motor out. Thanks guys.

Did you have the Heads machined after the first time it blew the Head Gasket?
It may have gotten hot and have a Crack in the Head if it's repeatedly getting Coolant into the Oil, it doesn't necessarily have to be getting it into the Combustion Chamber for this to happen. Does it smell sweet and white smoke?

it never really blew. The car ran perfect until i stripped a spark plug thread and had to pull the head. Then i put it back together and it was fine for about 200 miles before it leaked and i had to pull it apart again. never let it even come close to overheating so it is doubtful that the head is cracked

Did you have the Head machined when you pulled it?

Why can't you go conventional after you use synthetic because I changed from synthetic, to conventional about 6 months ago, with no problems?

he is trying to say that you CAN switch back and forth. He says that it is only a myth.

It's probably residual coolant in the oil from the swap. Change the oil and check it again.
