which roller rockers will fit on my 350 with the center bolt hole heads. i heard the full rollers wont fit because they are to wide... does anyone no for sure

and i forgot to ask, how much horsepower will they add.

u can get some for under 200 from jegs. u need the narrow bodied. but most are self aligning and if you are using guideplates i dont think u can use them. i have never noticed a hp gain when using them but all the dyno sheets i see say average of 10 to 15 at higher rpms

they dont make any extra HP but they do release some of the frictional HP loss
