But now how to alter or adjust cylinder pressure without effecting C/R or can't you?

the bottom line is cyl psi not CR & you want as much cyl pressure as your fuel will support wo pinging so if the build is in progress you want a higher static CR. If you're already together adv the cam (or a different cam), more (faster)timing and definitely the right cam/intake/carb to build as much intake mixture velocity in your desired rpm range to pack the cyls as full as possible.
