I ordered a set of C5917-060 on April 3 through Summit. Their estimated delivery date was 5/22/2020 at that time, and so far that has not changed. I think this part number made it take longer because they are not so popular. It's my first time ordering Cometic gaskets and I chose these based on their description that they were for Edelbrock and Engine Quest small block heads. These are 4.08" gasket bore for my 4.04" cylinder bore size. Waiting patiently.
