vtec swap in a 94 accord lx
 

hello,
im new to the honda scene, and im about to buy a 94 accord lx 5spd. it has the 2.2 nonvtec. the car needs a clutch and head gasket. it has 105k miles on it and im pickin it up for 300 dollars. I was wondering how involved it is to change it to a vtec setup. since im getting the car so cheap i figure i could probably afford to swap it, unless the gains arent worth the money. whats everybody think? also any good brands for parts better than others? thanks for opinions in advance.
