1942 Merc 239, 29A heads, assembling with Best composition head gaskets. There is a V shaped notch in one end of each gasket. Is this to indicate orientation? Notch to front or rear? The only thing I see that would indicate that they may be directional is that the two cooling hole openings at the bottom between the pairs of pistons is not the same size. Thanks, --

The V notch goes to the front. I think you'll fine there is a water hole on each end of the gasket, the bigger hole goes toward rear. Walt

Mike, mine was pretty greasy with surface rust where there was no oil or grease, but I found dark blue paint under all the gunk. The rebuilt engine is gloss black now. It's not a restoration so I wasn't worried about originality. The engine is going in a '29 roadster pickup. By the way, my engine came out of a fire truck.
