Could someone please explain the whole LS Vtec thing to me? How it works, What it does, how to install it, etc etc...

I'm confused before I read that it was just a gasket swap but I'm just curious.

I'm in the process of learning these things.

 

Research. This is a topic which has been beaten to death a million times. It is a B series swap, the most common swap into a 92-00 Civic.
