I dom not believe the rockers are 1.6 unless someone ordered special rockers for this engine. Most stock rockers for a FE are 1.76 ratio but will not check that. The cam card may be printed with that kind of lift since the SBF had 1.60 ratio. I think you need a camshaft in the 230/236 range but may be hard to find one with lower lift. The lift needs to be in the .530 range or below to work with the stock pistons more than likely. Good luck, Keith Craft
