Compression Check

Has anyone done a Compression test on a 100% stock XB Motor?
If so what where the numbers in PSI (I.E. 185PSI per cylinder)

I need to know what is/should be the number stock for comparison on something im doing

Thanks

Sorry this came WAY too late to help you, but resurrecting this thread for future reference.

The service manual calls out for:
Compression pressure - 1,471 kPa (213 psi)
Minimum pressure - 1,079 kPa (156 psi)
Difference between cylinders - 98 kPa (14 psi)
