The timing marks on the crankshaft and camshaft gears should be straight across and point at each other. Recheck the timing. Remove the valve cover and number 1 spark plug. turn engine by hand watch the rocker arms one number 1 cylinder,when number 1 piston comes to top 6 degrees before T.D.C the rockers arms should show both valves closed. Aline the timing marks.
