Ive been hearing about these things called 1.72 Roller Rockers. how much horsepower will it give me onj stock engine but i have a cold air intake and headers. what the hell are these Roller Rockers and what is a good kind? where could i buy them? are they hard to install?

roller rockers have a little wheel on the end of the rocker arm that makes it spin off the valve spring faster. they also make roller lifters. i've got a set of those and the 1.72 roller rockers, and they're a great match. roller rockers by themself won't give you a whole lot of horde power. however, they make the engine perform better especially when you upgrade thing like heads and cams

roller rockers really by themselves aren't good for much. i'd leave the stock ones in unless u going for a better cam or something at the same time. otherwise u'll be doing alot of work for ro reason.

Roller rockers are a nice compliment to even a stock motor because it affects your cam specs. (simple explanation is it makes the car think theres a bigger cam in it)But using them in addition to heads and a different cam is of course the way to go. Just dont over do it. 1.72's and an X cam will probably create some clearance problems. LOL
