Just checked the compression. I'm not sure of the accuracy of the gauge (it's been through a lot), but the cylinders were all consistent at just over 120psi.

Edit:
My testing methods (in case I did something wrong).
- Ran the engine for a few minutes to warm it up.
- Pulled the fuel relay
- Removed all plugs
