Pulled the cylinder head off and set it on the ground. Tilted it up on the timing chain side to inspect underside and these two dowels fell out from somewhere. I have no idea where they came from. Anyone know where they go? I have two dowels in the block itself still on the rear corners that I assume line up the cylinder head. These measure 13.50mm outside diameter, 9.40mm inside diameter, and 2.10mm wall thickness. Thank you for your help!

 

Never mind. Came out of the intake manifold. Don’t know how it stayed on the intake manifold bolts. But crisis averted.
