Harland Sharp SLS17 Roller Rockers Anybody running the SLS17 HS roller rockers? Anybody ever seen a before and after dyno test on these. 15 to 40 hp gain is a little hard for me to believe. I could see where it might be of some benefit for valvetrain stability. especially with the .639 intake lift on a MS4 cam. Whats the general thoughts on this.
