    FF block identification

    I had a nicasil 245 block replaced with a block that is sposta been ported out to the 245 specks. My current block is a FF with a 2-2-94 date code on it. Is there a way for me to tell if it has been modified or a stock 200hp FF block? I appreciate any info yall can provide. I would give original serial number but as the block has been replaced not sure its pertinent.
