Casting number 8796896 corresponds to a set of cylinder heads primarily used in GM's small-block V8 engines, particularly those from the late 1970s to early 1980s. These heads are typically found on 305 and 350 cubic inch engines and are known for their relatively low performance characteristics compared to other heads from that era. They feature a small combustion chamber, which contributes to lower compression ratios. Overall, they are often considered less desirable for high-performance applications.
3998993 is from 72 or 73 307 or 350. 75 cc chambers.
Cylinder head casting numbers are unique identifiers found on engine cylinder heads, used to determine the specifications and compatibility of the heads with specific engine blocks. These numbers can help identify the manufacturer, engine type, and model year, aiding in repairs, modifications, or restorations. When searching for replacement heads or performance upgrades, knowing the casting numbers is crucial for ensuring proper fit and function. Typically, they can be found on the top or side of the head and may require cleaning to be visible.
These should be double hump heads. They are very sought after heads.
Find the casting number on them... type "GM (insert casting number)" into a search engine and you should find what you're looking for.

The cylinder heads with cast number 8873370 are typically associated with the Chevrolet small-block engine, specifically the 305 and 350 cubic inch variants produced in the 1980s and early 1990s. These heads are often referred to as "smog" heads due to their design aimed at meeting emissions regulations, and they feature smaller ports and combustion chambers. They are generally considered to be lower-performance compared to other heads from the same era.
I was unable to find that exact number at mortec.com, however if you have a set of 3991492's, they are very possibly a set of 70-up LT1 camel hump heads with 64 cc chambers. These would be valuable heads.
No. The cylinder head on the Type R and GSR are different. The bolt and coolant holes will not match up. However, the Type R's intake manifold will fit a 99-00 Civic SI because their cylinder heads are similar.
Cast iron for a 307 or 350 unless they have 1.72" intake valves then its a 400 head
The casting number for a 1969 Chevrolet El Camino can typically be found on the engine block, usually on the driver's side near the front of the engine, or on the rear of the block near the bell housing. It may also be located on the cylinder heads or the intake manifold. Additionally, the vehicle identification number (VIN) can provide information about the engine type and specifications. For precise identification, consulting a service manual or reference guide specific to the 1969 El Camino can be helpful.
