    1.7 or 1.8 full roller rockers

    Are the 1.7 or 1.8 full roller rockers worth it? I'm pulling my motor again and thought about "upgrading" I wanna do a new cam this winter but if rockers will do the trick I would rather go that way. I have an aftermarket cam specs are 578 intake and exhaust, duration at .050 is 226 in and 230 ex, lode sep is 112. I have the ls6 intake I will be upgrading that to either a fast 92/92 or the new wieand whenever that hits the market. spec +3 clutch 4.10 gears. QTP headers, duals, underdrive, 160 thermo, 42# inj., volant cold air kit, and a ls6 motor. will I need tall valve covers and/or a new tune? Thanks
