a little bit....but not much. i put on mine with a cobra upper and lower and felt a difference, but it was only up top that i felt anything. youd probably be better off just saving up and getting new heads...kinda wish i would have done that.

really, thats pretty good. i have never taken my car to the track so im not sure how much improvement it gave me. you can definetly feel it up top...but i wasnt sure if it was from the rockers or the intake.
one of my valve covers is leaking oil, so i figure if i have to put a new gasket on i might as well put rockers on kinda confused though, i have stock heads so do are the rockers i want pedastal mount of stud mount?

yeah, a lot of people have to modify the valve covers. i just think it depends on what year it is because i think there was a year that had different valve covers...but im not sure. all i had to do was take off the oil baffle under the fill hole. three small screws and that was it.
