you have to take off the valve cover and the remove the cams to get to the head bolts. there should be 4,6, or 8 bolts dont remember. but when you get those out you will have to get new ones because they are stretchable bolts the old ones will not be good anymore. Then the head will come off. but before you reinstall the head you must remove any oil that is in the screw holes for the head bolts if not you will pull the threads on the block and it will be ruined. After that reinstall cams tourqe down everything to spec, set time , reinstall hoses etc.reset time then you will be good to go. good luck
