The engine is back together, but still will not start. It is turning over faster and sounds better on the starter, however is still seems a bit slow considering the high CCA battery and 2ga wires. I may order a new starter and see what happens, it could also just be the new engine. I started to pull the fuel rails to check the injector status but ran out of time as I have to leave town for most of this week. Try again next weekend. Thanks for the tips.

per the manual, there is not a lot of ways to screw up the valve adjustment. Actually I went a little light this time and only tightened 2/3 turn past when the pushrod quite turning (manual calls for 1 turn).
