Thanks for all the helpful answers everyone. Yeah, the head was quite heavy I remember. Another question I have is about the supports that hold the cam up. Not sure if I am remembering correctly but I unbolted those. Should I take the head and cam off together or can I leave the cam attached to the chain and sneak the head out from under the supports? If not I just make a few marks on the cam and chain for alignment, don't rotate the crank any, and my timing should be good to go? Or do I have this all wrong? Thanks everyone.
