wft seriously? isnt it a metal head gasket? the only thing i can think of is it wasnt torqued? or tightened improperly? or milled crooked, not sure about that, hopefully jack has seen this before and knows why or what the fix is

 

There is pic of gasket

 

I see the problem right off...your head gasket is on the gas tank...LMAO j/k
Never saw that before.
Hard to say what happened there but make sure you tighten the head nuts down equally.

 

What are the torque settings jack for the head

 

100-110 inch pounds.
