Re: Compression ratio of 327 head; year of the engine block?

The casting date will be the best information on the head itself, the casting number isn't particularly useful. Since you don't have a full history on the head the only accurate way to determine the current compression ratio would be to "cc" the combustion chambers and then do the corresponding math.
