Sent off a set of 706 heads to the machine shop for surfacing, valve grinding, cleanup and assembly. Super happy with the final product. They look like new.
These will be going back on a SBE Gen 3 5.3 with 250k miles on the clock. Original valves cleaned up with a double valve spring kit good for .600 lift. Sloppy Stage 2 cam 228/230. LS7 lifters, new lifter trays, trunnion upgraded rockers, FelPro MLS head gaskets, billet timing sprockets, New Melling oil pump.
Going with a truck intake, return style fuel rails with 80lb Deka injectors. Running a FiTech Ultimate LS ecm with trans control. Hoping for a solid 350hp and planning for turbo in about a year.
