Injector cup replacement

[Myerswelder]

I'm getting ready to replace my injector cups. I bought the Alliant Power brushes to clean the head up after I take the old ones out. My question is when installing the new ones do I just use red loctite or is there something better? Thank for the help.

Use the green loctite it is made for press fits.

Are you getting fuel into coolant? What is the reason for replacement

It all started when an o-ring blew apart and caused my motor to injector knock. It dumped so much fuel in my cylinders it hydrolocked it. When I pulled the injector the end was nasty with carbon build up. After looking at the hold downs they had all like came apart. 2 injectors were so stuck it took 2 of us with a pry bar to get them out. The cups are so nasty it'd be easier to replace them than to try and clean them up. This was how bad they were...
