Mr Gasket 5809G Ultra Seal Head Gasket RQF7A_KG975

Product details:

Gasket Bore; 0.038 i - Because of the technology available in today's high-performance engines, there came a demand for more durable head gaskets. Gasket responded to this challenge by creating the Ultra-Seal lineup. They feature excellent compressibility and high-temperature endurance, while not becoming brittle or brinelling aluminum cylinder heads. Their 5-layer composite construction sandwiches their patented Grafoil core material between two steel plates for strength, and a special elastomer coating is applied to both sides for leak-proof sealing protection. In addition, they're corrosion-resistant for compatibility with all types of fuel, and they won't require retorquing. 5809G fits these applications: FORD 7.5L/460 Ford big block 385 Series, FORD 7.0L/429 Ford big block 385 Series.
