They are more or less freshened up stockers, with a few upgrades. The bottom end has been freshened with stock parts. I added Cometic head gaskets. The cam and lifters are new, but stock. The heads are stock with the exception of conversion rocker studs and roller rockers replacing the non-adjustable stamped steel rockers. The biggest changes are in the fuel system. None of it is stock. The entire cool fuel system is gone, including the fuel filter head. It recieved a new filter head with 3/4" npt ports, #10 fuel hose and fittings, modified fuel rail, Aeromotive fuel pump, etc.
