Head gasket LEAK , I Fd up

...I had the same thing happen to my Magnum with the thin Mr G gaskets...really bad seepage-fouled the oil and was burning coolant. I just took them back off, cleaned the decks with solvent and 00 steel wool, and used the std Fel Pro permatorque blue gaskets, and it sealed up. Not saying that will work for you, but that's what I did. If you suspect your block is that warped, check it with a straight edge and feeler gage...if it's truly bad, you'll need to take it down anyway.
