		| 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.    |
