I think the only way that you will get the specfic part for your engine is from the dealer. I did a search on Advanced Auto for head gaskets for my 77 corvette 350. I then did a search for the 97 350 vortec head gasket. Take a guess it came back with the same felpro part number. The thing about it is the 77 came with a steel shim gasket the replacement felpro is a thick composite gasket.
