the main things with 300-6 is press in rocker studs [not screw in]...and cheapie rockers....also they never came with big valves and carbs were always single throats....but the ports flowed damn good......and the rest is easily upgraded...they came with timing gears not chains....replacing the aluminum gear is common.....and cast alum. pistons [also easy upgrade when rebuilding]...the later fuel inj. cast iron headers are a great cheap add on...add the 4bbl offy intake and roller cam and rockers [maybe an aluminum valve to] and you have one awesome 6 banger :biggrin:
