Intake Manifold
Seals - Intake to Heads
| Intake to Head - Hardware History. 1)2) | OEM Part Numbers | |
|---|---|---|
| 1957-78 | Used exact same port sealing machining, heads and manifolds | Uses O-rings - 27060-55 - Clamp 27063-57. |
| 1979 | Confusing because it had the o-ring machining but used rubber bands | Uses rubber bands - 27062-78 - Clamp 27063-78. |
| 1980-later | Made with “o-ring delete” machining. | Uses rubber bands - 27062-78 - Clamp 27063-78. |
| 1979 models could retro fit 78-earlier interface mechanisms as a bolt on mod. | ||
| 1980-later models needed the heads to be machined for reverting to the straight up o-ring seals. | ||
