Curious what's out there for a header for my 440 dart sport

So for you guys using the TTIs are you bolting them to the motor and dropping it in? Or can you actually install them with the motor in place?
I put the motor in from the bottom, lifted it a touch and it put them in right there. Worked beautifully. Only thing I had to beat on was my 450$ oil pan.
