Manifold off, now what?? Lol...newbie question

start by stuffing the ports in the heads with paper , then lay clean rags , towels etc in the lifter valley covering everything from head to head , when you get ready to put it back together get a gallon of old oil and pour it over everything with the drain plug out and a catch basin in place , I do this a couple of times to "wash" the crud off , I pour the oil through a paper filter to get the big bits out before pouring it through the valley , I then like to coat the cam , lifters and everything else that moves that I can see with some sticky red assembly lube . I have cast heads so I just use a razor scraper for the big stuff then a scrubby pad for the final clean .
