The Stovebolt Site Forums The Shop Area Engine Shop Mystery oil line - mismatched head

Post the various casting codes and serial codes/numbers on the block and head and people here will help identify its "origin". Post both head codes/numbers and block codes/numbers because you could (or, most likely you do) have parts from different years/models.
