+===== Seals - Intake to Heads =====
+^ Intake to Head - Hardware History. ((See Brucstoudt & Dr_Dick - XLForum - http://xlforum.net/forums/showthread.php?t=2079889)) |
+| 57-78 had the exact same port sealing machining, heads and manifolds - **They use O-rings**. |
+| 1979 is confusing because it had the o-ring machining but **it used rubber bands**. |
+| 80-later had the "o-ring delete" machining. **These use the rubber bands**.|
+| |
+| (If you had a 79 you could retro fit 78-earlier interface mechanisms as a bolt on.) |
+| 80-later needed the heads to be machined if you wanted to go back to the straight up o-ring seals. |
