I have an 80 Spitfire that I am thinking about taking the head off so I
can bump the compression to somewhere around 9.0 - 9.5 from the stock 7.5.
I rebuilt the lower end several years ago, but did not touch the head as
it was judged to be in fine shape and I did not have spare money at the
time. I am pretty sure the head is stock, but is there a way to verify
that before taking the head off?
I know that the only way to tell for sure is to measure the volume with
the head off, but I would hate to take the head off, then find out it
was already at 9.0 compression. So I would like to sort of confident
that there was a good reason for me to take the head off.
