okay just thought a little more deeply and you have to take the head bolts off. but here is what you have to do:
take off the valve cover (4 12mm bolts)
then remove the head bolts (10 17mm bolts)
then there are 3 screws on the rocker arm assembally that hold the rocker arms on then the rockers slide off and then you replace them.
then there are 6 12mm bolts holding the cam down
Not really that hard at all
