SK head |

The Medium Riser and the SK head use the same intake gasket. The exhaust port opening is also the same size. The difference is that the SK head has a huge bowl under the valves like a High Riser. The identical intake and exhaust port openings is how Ford got NASCAR to accept them as a replacement for the Medium Riser heads in 1966/67. |
