A complete top end kit for your '70 - '75 that has the Siebenrock cylinders.


  • 4 pushrod seals
  • 2 standard base gaskets
  • 2 head gaskets
  • 2 valve cover gaskets
  • 4 cylinder stud o-rings
Recommend dual plugging heads if using standard base gaskets giving 9.5:1 compression. Low compression base gaskets are also available (Part number 1111092) which lowers Siebenrock piston compression ratio to 8.8:1 allowing use of single plug ignition without the risk of "pinging".
