Features Unique to All Models for Continental Engines

       Improved Casting Integrity

• Castings meet stringent porosity and shrinkage requirements.
• Promotes a longer-life cylinder head, less prone to cracking. 
• Computer Generated Cylinder Head Fin Configuration .
• More consistent fin thickness and spacing.
• Means more uniform heat transfer and fewer "hot spots", compared to standard factory cylinders. 

      New Materials

• Advanced alloys yield 20% greater strength than aerospace industry standards for air-cooled cylinder heads.
• Increases cylinder longevity.

     Through hardened 6382 Steel Cylinder Barrel

• Through hardened 6382 Steel Cylinder Barrel. These barrels may be ground oversize and fitted with oversized pistons.

      Choked barrel

• Optimal barrel choke allows rings and pistons to work properly at normal operating .
• Improves performance and reduces ring and piston wear.

      Features Unique to Continental A-65, C-75/85/90 & O-200/300 Engines

     Improved Exhaust Port and Guide Boss

• Exhaust Guide Boss extends to completely surround the exhaust guide.
• Heat is conducted away from the guide to reduce valve sticking and wear.
• Exhaust port wall thickness has been increased to reduce premature warping and cracking. 

      New Ni-Resist Valve Guide

• Ni-resist exhaust valve guide and chrome-plated valve stem.
• A high performance improvement that reduces valve sticking and wear. 

      Rocker Shaft Bushings

• Factory installed bushings.
• Provide a superior bearing surface and simplify the repair process.

      Features Unique to Continental 470/520/550 Engines  

      New and Improved Rosan Inserts for Exhaust Studs (520 & 550 models)

• Improves exhaust union reliability. 
  Stronger Injector Boss
• Increased thickness has been added to the injector boss area.
• Helps reduce cracking.
  Strengthened Rocker Boss Area
• Thickened web size reduces cracking. 
  Increased Port Wall Thickness and Enlarged Spark Plug Boss .
• Exhaust wall thickness has been increased to reduce premature warping and resist cracking.
  
  Improved Port Design
• 7% better volumetric efficiency
• Smoother port walls reduce drag
