Turn the crank 90 degrees and then spin the oil pump again. Repeat both steps until oil comes up all the push rod holes. This may take a long time and can burn up anything less than a stout 1/2"drill. If you don't get oil to all push rods on one side, you could have blockage in the oil gallery that feeds the lifters on that side, but that's unlikely.

As you noticed, the rear bearing is grooved 360 degrees. Hopefully you didn't partially cover the journal holes when by installing the cam bearing too far forward or rearward. That's something I always check with a paper clip before installing cam and rear plug.

The 4 shiny gaskets are to partially block the heat riser passages. Not sure why the holes are the same size in both pairs.

The single gasket may be for an EGR valve. (??)
