TexasProton I believe that you have everything correct except for your
left Cam(driver side ). When you state that you had it sprung to the 9 o'clock position before rotating it to the timing mark, is this in relation to the timing mark on the head or a actual clock?
When the manual states to rotate the camshaft until it springs to the 9 o'clock position it is in reference to the timing mark on the head which means at the 11 O'CLOCK position on a clock. This is where mine was at. Then when you you rotate it again to line it up to the actual timing mark on the head, it will not spring back, requiring you to hold it in place while the belt is installed. This is exactly how I did mine.
Also when you go to fire it up you don't need to crank it over for very long you will know right away of its right. It should fire right up, if not then you are off. Thinking that's why your plug was fouled
Just a note: When I timed my cams this way it started at BDC it would not start at TDC
