You actually were right. Those plugs go in the end of the lifter oil passage. The only time they're ever used is during a complete build. The machine shop has to remove them to do their work, so you have to press new ones back in. But I had a few lying around and found them to be just perfect for cutting thules in the Stoetkit. Worked just like a thimble. Cheap too - You can get 'em at auto parts stores for less than a buck.
