    Intake 25-30 lbs ft
    Cylinder heads 65-75 lbs ft
    Main caps 100-110 lbs ft
    valve cover 3-5 lbs ft
    rocker shaft 30-35 lbs ft
    connecting rod cap40-45 lbs ft
    timing chain cover 20-25 lbs ft
    water pump 6-8 lbs ft
    water manifold 25-30 lbs ft
    harmonic balancer 200-220 lbs ft
    exhaust manifold 10-15 lbs ft
    Hope this helps, Tim McCluskey
