Andrew -

There are a few ways to tell what engine you may have.

Intake Ports on the Head:
40HP - Studs are vertical, straight up.
1300-1500-1600 - Studs are at angle (about 15 to 20 degrees)

Barrel Heights:
1300-1500-1600 Barrel Height is the same on all three displacements.  The
only way to know for sure is to pop a head and measure the cylinder inside
diameter:
77mm = 1300
83mm = 1500
85.5mm = 1600

Engine codes:  This can be a problem, as the codes for "down under" are most
likely different.  From my Factory Engine Survey:

E=1300 (M240 Low Compression)(Non-USA)
F=1300 (USA)
H=1500
L=1500 (M240 Low Compression)(Non-USA)
B=1600 Single Port
AB=1300 Dual Port (M240 Low Compression)(Non-USA)
AC=1300 Dual Port (Non USA)
