Porting and polishing is enlargening and smoothing openings in an engine. You use a carbide bit, and drill away at it. You can make the parts flow better, and increase power and longetivity. The biggest improvement on my own will be the cam. No one'* done major porting on L27 parts that we know, so whatever increases I see will be the first.
Most modern hoses will be fine if your fluids are regularly changed, and the engine is used.
Don't worry about those for now.
When i'm swapping all these modified parts to my car i'll be replacing all the gaskets. That' will help a lot with durability and longevity.
