I did not see the most important : Tackling the reason why the head gasket failed.

Diagnose !
It is typically a clogged radiator.

 

Good advice.

I might get spare heater pipe o-rings. They get damaged easily if you're not careful reinstalling the heater pipes.

Shame to hold up the project for a few days over a 50 cent piece of rubber. Happened to me...

 

You need a breaker bar.
You need a black impact grade 5/8" socket for head bolts
You need an iron pipe - like from a floor jack handle.

You need a torque wrench.

and a parking lot to fix it in
