flat tappet vs roller cam

[SS Shaun]

Ok guys and gals i was at a cruise the other night and a lot of guys got into a convo about cams. and they started to argue about roller cams how mechanical is better then hydro and so on. So it got me thinking about my cam in my car. I currently have a flat tappet cam and i know you have to do the whole break in process and all that. but i wanted to see what you guys think about this topic. since i have my intake off right now should i think about converting over to a roller cam setup? besides cam and lifters anything else i will need? like change my push rods? my rockers? and so on
