Delphi manufactures a number of aftermarket replacement parts. If Delphi says a specific part will fit your car, you should have no problem.

Replace the oring and seal. I can't remember if the line swivels. If it does then there is a seal it there. If it's a solid fit. Either you have a dirty end or the line is wrong and needs the correct fitting.

IF the light is on, a trouble code is stored. Get the code read. There's no way to know which wheel speed sensor is bad without the code.

If the brakes are spongy, there is still air in the lines. Are you sure that you are using the correct technique to bleed the brakes as it is generally a very simple job to get all the air out.

Check motor mounts.

t there is no mechanical speed governor. It is controlled by the PCM - engine computer which you would have to reprogram to increase the limit. Dealer only

The most probable cause of both problems is with the replacement heads. As far as knocking goes, hard to diagnose from here - usual causes are a noisy hydraulic lifter (which, if severe, should be replaced) or a failing piston bearing or incorrect head/head gasket (piston banging on head which is very serious). Also, if the head gaskets were incorrectly installed or the wrong heads were used, you could have blocked some of the cooling water ports. Overheating can also be caused by a blocked radiator - the system circulates the cooling water into the bottom of the radiator and the water cools as it circulated up to the top and back to the engine. A quick way to check when overheating is to CAREFULLY see if there is a hot-to-cooler temperature gradient in the radiator from bottom to top.

Could be any number of thing's . Testing before replacing parts eliminates waste . If you don't know how to test , your best bet would be to take it to a qualified repair shop that does.
