Header installation

I'm going to pick up a SS DC header probably at the end of this week and I have a couple of questions:

1. Is the installation easily done with basic tools and a jack?
2. What are potential problems with a self installation?

A friend of mine says that he will install the header. He installed his header on his 90-something civic. Should I trust him with the installation or should I pay my shop $50 to istall it for me?

Thanks guys
