Need help! 4.7l

Greetings all
I need some help figuring out this engine problem.
05 4.7l heads redone. New seats and valve seals along with HO cams and lifters.
New coils helped some. New lifters also helped some then went backwards.
No engine codes.
Ideal slightly rough and has a small surge in the rpms at constant speeds. Seems more prevalent at the 20,30,40 ranges but does happen at 60
Heavy lifter knock on drivers side.
What am I missing?
Thanks
Jesse
