Product Details

The Cometic C9710 is a premium copper head gasket designed specifically for Harley-Davidson Evolution 1340 engines. This high-performance gasket features a 3-13/16 inch (3.8125") bore diameter with a .010 inch thickness, providing precise compression control and superior sealing capabilities.

Key Features:

  • Premium copper construction for maximum heat dissipation and conformability
  • 3-13/16" (3.8125") bore diameter designed for HD Evolution 1340 big twin engines
  • .010" compressed thickness for precise compression ratio tuning
  • Embossed design ensures excellent sealing under extreme cylinder pressures
  • Reusable design when properly installed and torqued to specification
  • Ideal for high-performance and racing applications

Cometic copper head gaskets are engineered to withstand the demanding conditions of high-performance engines, offering superior thermal conductivity compared to composite gaskets. The soft copper material conforms to imperfections in the cylinder head and block surfaces, creating a reliable seal that maintains compression and prevents leakage.

Found the part I needed when it was sold out everywhere else. Thank you!

The tool I ordered came quickly, I've tested it out already, works great. Very pleased. Thanks!

Very best price on the net, actually more than half off. Now lets see if I get my order and how long it takes.

Great

This part was hard to find and Mr. Clint Rathfon was very helpfully and he emailed when the order processed and when the order shipped. Because of him I will make sure me and all my friends buy pay parts from this company again and again.

THMotorsports had the part I needed in stock, unlike other suppliers. The price was good and it shipped quickly. I will shop here again.
