Intake side, makes sense. I guess I will order up the new ones and see what they look like. I am probably seeing the old ones sitting atop the guides I guess. I just assumed they would come out on the valve stem. The socket does only open on one side as you sagely note. But its a wide enough opening that I think I can just place one keeper on the stem then push/slide it around the stem to the rear(of the orifice) and then just put the next one on the front...we shall see. One final question before I end this thread, after having gone done this work to the head it makes me wonder how much I should do the block. Oil pump has 225,xxx miles on it, I wouldnt mind replacing it and affirming the pick up tubes connections. Rings, I never measured the compression...and if I am doing the rings I guess new bearings on the crank wouldnt be a bad thought either...am I getting in too deep? Should I just clean and cut the head and slap it together? Decisions decisions!
