There was a good program on how to determine the compression ratio on
"Performance TV" on the The Nashville Network a while back. As I
recall, they used a liquid to fill the cavity of the head in order to
get that part of it exact. If you watch that program (or it might have
been one of the other Car related TNN programs) they will probably
repeat it, they usually do several times.
