Freeze Plug Question

Part number 830007 from Pioneer is all brass expect the really small pair that goes behind the cam thrust plate, the threaded plugs, and the rear cam plugs. Also, this one comes with both styles of rear cam plug. These brass plugs are not quite as deep as the typical steel plugs, but they work nicely for me. Note: I always use a small amount of sealer on them as well, for both steel or brass styles.
