This is a pair of original GM cylinder heads for a Big Block Chevy Engine. The casting number on each head is 3933148. The 3933148 heads were used on 1969 Big Block Chevy truck engines and possibly others. These heads have the large oval port intake ports. The combustion chamber of these heads list as being 113cc which is considered a open combustion chamber design. These heads are for Gen IV Big Block chevy engines. Please confirm your specific application.
These heads are in good core condition as shown. These came to me out of the estate of a long time hot rodder and were in his personal stash for a future engine build. The heads are complete with valves, springs, retainers, guide plates, and screw in rocker studs as shown. The heads look to be completely stock and I do not believe they have ever been rebuilt. All threads are in good condition with no helicoils or thread inserts. These are awesome unmolested original heads that are ready to build to your specs.
This is your chance to own OEM GM Big Block Chevy heads for your special engine or collection at a GREAT PRICE. Don't Miss Out!
Please note these heads will be disassembled for shipping with the hardware shipped separately in order to keep the shipping costs down.
