Head Gaskets
I used the Mr. Gasket MLS gaskets and ran into the same issue. On mine, if I remember right one rivet would get pinched between the head and block but if you turned it around it fit good. But I did ruin one gasket. Then after running the car for half a season they started leaking. I'm back to the 1008. Why I tried the Mr. Gasket's I'll never know.
