Solutions for too much compression

That might not be accurate enough especially with hydraulic lifters, and just eyeballing the dampener as opposed to actually having it degreed / or degree wheel. ALSO has the TDC mark been confirmed with a piston stop? You know how to do that?
Thanks. Yes TDC has been confirmed with a piston stop. And I realize my rocker watching method is not perfect, but I figured it is telling me that the cam is pretty darn close. And I didn’t have to tear anything apart yet.
Really, the motor doesn’t run bad, I’m just trying to make it run great.
