Mac LT question?

[CPB00GT]

I had Mac long tubes installed on my car recently. The passenger side header is leaking bad. I want to install a new gasket. I have read some right ups on the header install itself, but don't know what work is involved in just a gasket swap. Will this work to get at it? Take off the front wheels and the x pipe. Unbolt the motor mounts, and jack up the engine. What else if anything needs to happen for me to take the passenger side header loose from the head?
