Hi all,is it possible to fit the head gaskets the wrong way?,ive noticed when painting engine after assembly that the left side head gasket (front on)has part of the head gasket protruding like a tab. on the right side head its at the back of the head on the right side,will this be a problem?if I have to dismantle the heads could I use the head gaskets again? The engine hasnt been running and getting parts in nz pretty much impossible
