Shipping was terrible. It took two weeks to receive it from California to Missouri nobody asked for a casting number to make sure I got the correct Cylinder head and I don’t understand why some freeze plugs were put in in somewhere not and it had extra holes in it that I did not need and I had to try and find special plugs for and it also there is two holes, not drilled in the head that I had to drill and tap for mounting brackets
