This is a pair of OEM GM cylinder heads for a Big Block Oldsmobile engine. These heads recently came out of the estate of a life long Oldsmobile enthusiast. This owner has collected a good number of factory performance parts and I plan to list all of them here on Ebay as time allows. The casting number on these heads is 413191 and the casting mark is Ka as shown. Please confirm your specific application.
These heads look to be in good original condition as shown. These are guaranteed to be crack free cores for rebuilding. The heads are complete with valves, springs, etc. There is no porting or modifications that I can see. All valves sit high in their seats. The exhaust valves look to have hardened seats which is a huge bonus. Don't miss these awesome OEM GM Big Block Oldsmobile cylinder heads.
This is your chance to own the real deal factory Big Block Olds cylinder heads you have been searching for at a GREAT PRICE. Don't Miss Out!
