Yes but praying someone can offer some tidbit I havent already tried. I have deduced that the timing is DEFINITELY the issue but cant seem to correct it. The ENTIRE ignition system, sensor and all was sent to Daytona and it ran fine on their engine. Put back on mine and it doesnt run. No one can explain why.

Are you sure the wire harness plugs to each valve cover coil assy didnt get swapped backwards? IE, driver side harness plug in passenger side ?

THIS

If you've ever dealt with this you'll never forget. Had it eat my lunch one time after a buddy swapped his coil harnesses and I didn't know they were out of whack.
