You can just make out the shadow of the cylinder bore and the plug hole is right on top of the outer edge.
As a point of note, my 33RP has this head fitted and has run without problems for several thousand miles. The difference in torque compared to the Low Compression head is impressive, but you need to be wary of ignition advance if you're using an Austin crank... discretion is advised!
I use B5HS plugs.
