I'm considering them. Are they an easy install? What needs to be removed to install them? Could I port out the stock ones myself and what would I use to do it?

To do them right you will need a welder to add metal to the front manifold for port size matching to the rear, and also to weld the rears externally.
A Dremel will be needed to gring the original internal weldsw from the rear manifold.

You better not even THINK about using a dremel on those. You'll be older than VENOM by the time you're done. Even a die-grinder won't be easy.
There is no 'precise' to worry about. You grind out the factory OEM welds, nothing more. Otherwise your tubing is too thin.

Were these Cast Iron or Tubular Stainless?

I can tell you from experience, as I think I'm the only person here to ever SELF-port L27 or Series 1 L67 manifolds, you're not going to be doing any porting on them with a dremel.
CAST manifolds are a different story. It won't be easy, but a dremel will work. Cast Iron is brittle, and has very low tensile strength.
