Does the oil line go in the cam cover or to the back of the cylinder head?

Its a little odd going to the cam cover, but in doing so would likely mean the oil passage to the lash adjusters and cam is intentionally plugged and the external line is feeding both the lash adjusters and cam "bearings" and lobes.

If it is going to the rear of the head, then it likely has a sealed off tube letting full oil pressure the cam and lobes, but lower psi to only the lash adjusters. Which is how I have mine set up.

I would prefer to have the higher volume and pressure going to the cam and keep the low pressure regulation to only the lash adjusters.

The oil line connects to the stamped steel cover at the rear of the camshaft, not the head.

Since the regulator is set at 6 psi, increasing RPM will not increase oil pressure. This seems counterproductive. If an engine oil pump is producing only 6 psi at idle most would be concerned, and even more concerned at higher RPM.

There is quite a bit to unpack about this engine and I just want to be sure there is nothing that needs correction. It will be difficult as the B-J buyer knows little about the car, and the previous owner to him and the builder remain unknown.
