When the crank is at zero the lob over the intake valve shouldn't be pointing staight up from surface of the head because the exhaust valve would then be opening, given the fixed relationship of the intake and the exhaust valve lobs on the cam. Remembering my 4.5 when the crank was at zero the lobs formed a V, intake at 10 o'clock and exhaust at 2 o'clock as I recall.
