Chevrolet Gmc Part No: 3782461X

Manufacturer: Chevrolet Gmc

Part Number: 3782461X

Remanufactured heads with new parts.

Up for sale is a very rare pair of professionally rebuilt Small Block Chevy 461X double hump fuelie cylinder heads. Casting number is 3782461X.
These heads are Flint castings, so they will be correct for a Corvette or passenger car restoration. The heads are dated L82 & B162 (December 8, 1962 & February 16, 1963). These heads were used on the 300, 340, & 360 horse 327s in 1962 & 1963 Corvettes and Chevrolet models. These heads have 62cc combustion chambers with new 2.02” intake valves and new 1.60” exhaust valves. The 461X is very rare and one of the best closed chamber cylinder heads of the early 1960’s. Heads have been hot tanked, shot blasted, & magnafluxed. These heads have been completely rebuilt with 8 new hard exhaust seats for unleaded fuel, 16 new thick-wall valve guides, a 3-angle valve job, 8 new 2.02” intake valves, 8 new 1.60” exhaust valves, & 16 new high-performance LT-1 / Z-28 1.25” stock diameter valve springs good for up to .500” valve lift.The heads have also been resurfaced .007” for a perfect head gasket seal. Heads are then thoroughly washed and fully assembled with 16 new OEM “O” ring seals, and 32 new heavy-duty valve spring keepers. All valves and valve seats have been checked for a perfect compression seal. There is no porting or polishing on any intake port, exhaust port, or any combustion chamber. All threaded bolt holes are good (one head has Heli-Coil thread repair inserts in two exhaust bolt holes). The heads come as pictured and are ready to install. The heads pictured are the actual heads you are buying and will receive. The double hump heads were factory installed on all High-Performance Fuel Injected and carbureted Chevrolet vehicles including Corvette, Camaro RS SS & Z-28, Chevelle Malibu, Chevy II Nova, Bel Air, & Impala. These heads will also interchange with other camel hump heads with casting numbers 461, 461X, 462, 291, 292, 186, 041, & 492. These heads will fit all 265, 283, 302, 305, 307, 327, 350, & 400 small block Chevy engines from 1955 to 1986 with no modifications (steam holes will need to be drilled for a 400) and 1987-1999 with correct intake manifold (except 1992 & up LT-1 reverse flow). I tried to list everything about these heads but please ask any/all questions before buying. Payment must be received within 3 days or item will be re-listed unless other arraignments have been made in advance. Shipping, handling, & insurance is fixed at $95.00 for both heads shipped to the continental US only. Alaska, Hawaii, Puerto Rico, and everywhere else will be higher. All international bidders please multiply the shipping calculator by 2 for two boxes. If you are outside the continental US & purchase the heads, please do not pay until an adjusted invoice is sent to you with the added additional shipping costs. Thanks for looking.
