[QUOTE="RWtorque, post: 10749932, member: 103566"] Sometimes roller rockers/followers can make a ticking sound but it's hard to tell since we can't hear the noise ourselves. I upgraded to a billet 1.8:1 rocker on one of my Stangs. I got about a 18hp gain as well. They were very quiet. Not sure what ratio you can go with on these engines yet though. I have not gone into the internals of this DOHC 4.6 yet. You could pull the covers and check that they are all torqued to specs etc... [/QUOTE]
