My are the same way, .300 lean on all of them . I'm using Isky red zone lifter, center on the exhaust, 1.80 on the intake. I have call evey one I know (that I trust), in cluding Blown6, T&D, smith Bro., and Isky. They all said that I sould be fine, or I could have a custom set of rockers made. T&A said $62.00 each on the intake, and $48.00 each on the exhaust. I'm just wondering if DSL would have some in put.
