This is what happen to me twice. After I put my heads on it was leaking oil all ofer the place from the drivers side vavle cover gasket. What had happen is when I took the gasket out of it was all bent up like they always are. I put it on and it was leaking well when I took it off, I saw that it had push inside of the head toward the valve spring and totally missed the hole, so the bolt was holding it in as it just went around it. The ther other the gasket had two metal crush washers in it and I didn't notice when I put it on till it started leaking and I had to take it off. It's a easy job if you know how to take off the intake. Good Luck!
