Tyler most book and net listings leave out the 6015 number. That is Fords number for a production engine block. So C2AE-6015-J is the correct number for a 62 406 block. The heads are also 406 heads. The number is 6090 and that is the same deal as the block number...just for heads. So everything is fine there. You should also see a "HP" cast on the side and back of the block.
