  • Kit Includes Cylinder Block With:
    • Strong, Wear-Resistant Alloy 7075 Tappet Guide Blocks Installed

    • Exhaust Tappet Oil Feed Retained
  • For An Additional Charge, We Offer Total Seal™ "Gapless" 2nd Ring Technology Which Provides Superior Sealing, Raising Effective Compression & Providing More Manifold Vacuum.
    (Note: Raising manifold vacuum may result in mixture changes. Be prepared to re-jet carburetors. It is strongly recommended that a quality valve job be performed and Total Seal™ recommends the installation of positive style valve guide seals to prevent oil from possibly being drawn through the guides due to increased intake stroke efficiency.)
