We are ready to start assembling my Son's 455 and are doing it today. We spent yesterday scrubbing and oiling all the parts that came back from the machine shop. However, we have a little question. We told the machine shop to leave out the brass freeze plugs as we are going to polish and install those separately after the engine is painted. They misunderstood, and left ALL the galley plugs out, even the ones inside the motor.

In the bag of new galley plugs we had a threaded one that goes deep inside from the rear (the machinist warned me to make sure that one was in or zero oil pressure) That one is in place now. There was also the large one that goes at the rear of the cam. There is also a 29/32 one we installed in the final hole in the bellhousing area.

In the front under the timing cover we have two screw in plugs, and we have installed those. That takes care of every hole, except for the 6 on the sides that we will put in after paint. The problem is, there are two more tap in style plugs left in the bag. One is about the size of a pencil eraser and the other has 15/16 stamped inside. Do they give you additional plugs in these kits to fit other applications, or did I miss where these go?

I can't call the machine shop til tomorrow and we are putting it together today. Any Olds experts out there? I tried going on line to find a schematic of Olds galley plug locations, no good. Thanks for any help.
