port/polishing a 5sfe, characteristics and bennifits? Options

[saleeka]

Im debating whether or not to have this done. I truly dont know exactly how this works, or what is done to what, but i'd like to know because it has been thrown at me to add a few hp. If anybody knows, does the characteristics of the engine change all that much? I'd assume a slightly quicker rev with a small loss in low end grunt for top end power- is this true? Also, where should I take my car to get this done? Im already getting my head gasket fixed at my toyota dealer- would they be able to do it when thats being done, or do I need to take it to a specialty shop? Anybody know how much one of these runs? Sorry for my complete ignorance on this subject but I'd love to gain the knowledge.

What it will do is increase the amount of airflow. It won't do much on a stock engine. It's good for highly modded engines. It will take more work that just doing when changing the headgasket, the whole head has to be taken out, it takes some work. I'm sure you could find a shop to do it for about $1000-$1200
