I'm sorry but I'm now lost haha...

If I am correct in my re reading of what has been posted,

Head is replaced? (Reman)
Intake gasket redone?
Timing items replaced?
Coils swapped?

What is a phaser....?¿????????

Any other items??????

I'm leaning towards a miss step when putting it back together.... Are you one hundred percent sure you got the timing correct?
I know modern engine can advance/retard ignition but will it be able to if timing chain was incorrectly​ setup???? Or possibly your bottom end is having trouble????

 

What were the compression readings for each cylinder?

 

Oh, what was the $1220 charge at the dealer for?
