Doing a 68 340 at the moment and having a hard time finding gasket set specifically for 340 but seeing alot of 318 kits I know they are near identical can someone tell me the difference? thanks in advance for any answers

You need to keep looking. 340 gasket sets are out there. Did you try Rockauto for your application?
