Rebuilt 2.02 Sbc # 461 Double Hump Fuelie Cylinder Heads Chevy # 3782461 on 2040-parts.com

Up for sale is a professionally rebuilt pair of date matched Small Block Chevy 2.02 double hump cylinder heads. Casting number is 3782461. The heads are dated E15 & E175 (May 1, 1965 & May 17, 1965). They have 64cc combustion chambers with new 2.02 stainless intake and new 1.60 stainless exhaust valves. The 461 is one of the best closed chamber cylinder heads of the 1960’s. Heads have been hot tanked, shot blasted, and magnafluxed. These heads have been completely rebuilt with 8 new hard exhaust seats for unleaded fuel, 16 new thick wall bronze valve guides, a 3 angle valve job, 8 new stainless one piece intake valves, 8 new one piece stainless exhaust valves, & 16 new performance chrome silicon valve springs good for up to .550” valve lift (closed pressure is 110# at 1.800”, open pressure is 325# at 1.200”). The heads have also been resurfaced .007” for a perfect head gasket seal. These heads are also machined for screw in studs with guide plates (not included in the auction). Heads are then thoroughly washed and fully assembled with 16 new premium Teflon valve stem seals and 32 new heavy-duty 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 one Heli-Coil thread repair on an intake bolt hole & the other head has a Heli-coil thread repair on a valve cover bolt hole). 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 gen 1 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.

Shipping, handling, & insurance is fixed at $90.00 for both heads shipped to the continental US only. Alaska, Hawaii, and everywhere else will be higher.
