port matching vs gasket matching?

Hi everyone, Im a bit new to all the nitty gritty parts of engines and cars etc. I was just wondering what kind of gains can be had by port matching or gasket matching? Is one better than the other? I assume they both need machine shop work? What exactly are you matching? Are you matching the intake ports on the intake manifold to the cylinder heads or are you matching the exhaust ports to the headers? Or both? Im really interested in learning more about engines especially all the little things like this that may not seem to affect a whole lot but when you put all the little things together they help alot, kinda like saving your change in a jar 50 cents may not seem like much but in a few months you could take the honey out to a nice dinner...... or buy some spark plugs or something lol.

Thanks Steve

I recommend you start with a little reading, one of the best books I've ever read on performance is Four stroke performance tuning by A. Graham Bell. It's hardcover and Amazon has it for $25 here
http://www.amazon.com/Four-Stroke-Pe.../dp/1859604358

It's not about a specific engine like say small block Chevy but covers engine performance from top to bottom and goes into greater detail than most books but is quite readable. If you want to understand WHY things make more power and how the whole package must work together I haven't found a better book.
