We now have reasonably priced MADE IN THE USA head gaskets (shop OEM prices) for the 65+cc engines. These gaskets are custom made from 5052* Aluminum alloy in the fully annealed condition for that perfect seal. Precision cut, yet a tad thinner at .025" than stock (.029") to raise compression slightly.


Head Gasket for 67cc-"80cc" Chinese Engine that has 8mm studs
Aluminum head gasket, .025" thick.
The gasket is thinner than the stock and will increase your compression ratio and increase horsepower.
This will fit the 67cc, 69cc, 70cc and the so called "80cc" engines

We will have 49cc 6mm and 67cc 6mm head gaskets soon!

*5052: This is the highest strength alloy of the more common non heat-treatable grades. Fatigue strength is higher than most aluminum alloys.In addition this grade has particularly good resistance to marine atmosphere and salt water corrosion. It has excellent workability. It may be drawn or formed into intricate shapes and its slightly greater strength in the annealed condition minimizes tearing that occurs in 1100 and 3003. Applications: Used in a wide variety of applications from aircraft components to home appliances, marine and transportation industry parts, heavy duty cooking utensils and equipment for bulk processing of food.
