I sanded mine flat and used anaerobic sealer on the edges, probably didn't make any difference. Do you make the slot to help lube the gear, or was that already done. I like the detail you do with assembly, and parts prep, really makes a difference in the life of the engine. All those things that no one sees, and no idea you even did them. ; )

These thicker plates have the groove already in them. The factory Pontiac pumps with the thick cast iron plate, did not. I have seen pumps with the thin plate gush water out of all four sides when flushing them out after washing. They leak really bad. Have not seen that at all with the 1/8" plate.
