Could you possibly have a brake booster that is leaking brake fluid, getting pulled into the vacuum port that is close to the rear cylinders?

The vacuum seems low. You can either smoke the system, to see smoke coming out, showing a vacuum leak. Or you spray carb cleaner at items near number 6, trying to locate a vacuum leak. The engine will some out when consuming the carb cleaner.

Do you have any pictures of the spark plugs? Also, pictures of the cam shaft and valve train would be helpful. Possible a cam lobe that has gone bad or maybe a damaged valve guide, that was not installed correctly when you had it rebuilt.

Maybe the ECU is commanding #6 more than it should. If you replaced everything and still have the same issue, look at what controls it all and that is the Megasquirt ECU. Look into your files, see if your settings are the same. I have no experience with mega, just being a technician and looking what controls it.

Zcardepot is a little cheaper than MSA, if you go with the early years sending unit. The early is only 2 wire and does not or may not illuminate the low fuel earning lamp, but level will work the same.

AEM's EPM provides precise engine position using dual zero-speed optical sensors, which offers the advantage of immediate signal generation regardless of engine speed. The EPM easily adapts to any positive-drive, half-engine speed device such as a cam or distributor drive, and can be used with any aftermarket engine management system that recognizes a 12-tooth crank 1-tooth cam pattern.

If it is top left, those are poly. If it is top right, then they are stock style and need to be pressed in. The item that is having something pressed in or out should not be damaged, if done correctly. So, need to see pictures to tell if they used the wrong die to press out the old bushings and possibly increased the diameter of the control arm opening on accident.

There are no new rubber stock bushings, most likely you are using polyurethane bushings with a separate internal sleeve. Is the fitment excessively small or allowing the poly to slide thru by simply placing the bushing in? If you were to use stock style, then you would be having the same shop press new bushings in. To me, nothing is damaged. Just fit the bushings in and put back on the vehicle. Please provide photos of the bushings and control arms, that way we can give you better answers to help you out.

Did you just disconnect connectors on the amp or did you cut wires to remove the amp? We can't tell you if easy to connect back up and for your issues to go away, because you didn't state how you removed the amp. Providing pictures are always best the more vague questions are. You might have had a 12 volt ignition source that was connected to the amp when the vehicle was in accessory or on position.

They attach to the hatch, with hinge at the top and latch at the bottom I believe.

Sent you a PM. Wasn't able to make it storage today, but will be heading there tomorrow.

Well, this is a Datsun Z site. With many using all forms of motors and transmissions and everything else under the sun. If the motors flow the same as the L28, then the rear goes to the inlet or top of the heater core and the other line looping to the front connection.

Not the most knowledgeable about Datsuns like some others are here. But I believe the heads for the Z are interchangeable, with same sprocket used from 70-83. The head you took off, the cam retainer plate bolts are loose and let the cam walk. The new head, the cam is retained properly. Are the lobs centered on the old head or are they offset, showing the cam has pushed towards the front? Why are you changing the head?
