Oil pressure is checked off the main oil gallery at the front of the crank case (you will see the horizontal oil passage that is the main feed for everything).
Do not be surprised if you have oil pressure down at the test port -- we have discussions about this periodically as
what counts is oil pressure up at the cam and we don't measure it there. Why not is a good question ....
You will find the following oil passage pictures to be good information on how the oil gets up there.
You will note the long screw by the upper cam chain sprocket on the top picture that makes the passage up through the head casting. If you were to loosen this screw and crank the engine oil should come welling up in quantity past the head of the screw if things are working correctly.
Re tightening the screw down to 100 inch pounds of torque will reseal the passage (crush seal on a brass washer) so the junction can be loosened, checked then re tightened with no damage to the functional oil seal.
Like I said, don't be surprised that you have OK oil pressure and a volume of oil going up through all the passages -- your issue may be the oil itself isn't doing the job that oil used to do ....
(reference oil war thread for why)
