OEM GM 3927186 Cylinder Heads Small Block Chevy Camel Hump 202/160 Valve Aug 68!

Description

This is an original pair  of GM high performance cylinder heads for Small Block Chevy engines. The casting number on each head is 3927186. 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 particular heads have 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 casting dates of H 7 8 and H 8 8 which decode as August 7th and 8th, 1968. This is a real deal pair of date matched factory 2.02/1.60 valved camel hump heads.
This is a very nice unaltered pair of original heads. They are
complete with valves, springs, and retainers as shown. When these heads came to me, I do not believe they had ever been apart before. They were disassembled to strip them to bare metal and check for cracks. There was one small crack found at a rocker stud boss as shown. I decided to leave this as is since there are many ways to repair it. One option is to add screw in studs and guide plates which many buyers would have done anyway. When the bosses are milled down to accept the guide plate, the crack will be gone.  The intake and exhaust ports are completely stock with no porting or modifications. The valves and hardware are all original GM pieces. I imagine they will all be replaced during the rebuild process but it is pretty amazing to find such a virgin pair of high performance heads. All threads are in good condition with no thread inserts or helicoils. These heads are being sold as cores for rebuilding which many require new valves, springs, guide work, surfacing, etc. These are awesome very early production date matched heads. Don't miss them!
This is your chance to own the original 2.02/1.60 3927186 heads you have been dreaming about at a GREAT PRICE! Don't Miss Out!
