Dave your tip on the guide bolts to drop the head onto was perfect. I've tightened down the head to 80 lbs, and placed the rocker shaft. I'm wondering why the exhaust valves on #2 and #5 have a huge gap to the rocker arm? Will this change as I rotate away from TDC on #1 when I go to adjust the valve lash? I'm at the pointer on the flywheel, so what gives? Can anyone chime in?
