  • Condition: This is an original GM cylinder head for Big Block Chevy engines. The casting number is 3856208. This head has the high performance rectangular intake ports and closed combustion chambers. The 3856208 cylinder head was used exclusively on 1965 L78 396/425HP and 396/375HP(Z16) engines. That's right, this is a 1965 only cylinder head that was only used during the second half of the model year after the 396 engine intro. The date code on this head is F 16 5 which decodes as June 16th, 1965. This is an extremely hard to find 1965 HI PERF head. This head is in very good condition overall with valves, springs, and retainers as shown. It has been inspected and is free of cracks and other damage. There is no porting on the intake or exhaust ports. The valves are the stock sizes which are 2.19 inches on the intake and 1.72 inches on the exhaust. The deck surface is very thick as indicated by the deck indicators on the outer corners of the underside.
