This is an original GM pair of high performance cylinder heads for Small Block Chevy engines. The casting number on each head is 3991492. This casting is known as a "camel hump" or "camel back" head due to the double humps cast into the ends of the head. The camel hump heads were reserved for the higher performance Small Block Chevy engines.

These heads originally came with the larger 2.02 inch intake and 1.60 inch exhaust valves which were used on the Z/28 302 engines, LT-1 350 engines, and other solid lifter applications. These heads have the very hard to find angled spark plug bosses that angle the plugs towards the exhaust valve for a better flame pattern. These are very hard to find heads. These heads are in good original condition as shown.

They just came out of the estate of a hot rodder who had them stashed away for a future project since the 80's. They have been magnafluxed for cracks with none found. There is no porting, modifications, or repairs to these heads.

These heads are awesome unmolested cores that are ready to machine and build to your specifications. This is a very hard to find pair of factory high performance camel hump heads.
