I have an Olds Cutlass F85 with a 225 V6, both heads are cracked. If the cylinder head casting number is B1358676R, would that be the only head that will fit my block or are other heads with different casting numbers interchangeable? I saw this reference chart under the reference tab and need help to understand what it is saying:
