Plus a new cam makes the valves happy, which makes them seat better. LOL

but the cr isnt based off of how much air/fuel ends up in the cyl. the compression itself might change a little, but the ratio isnt going change enough from the valves moving that slight amount to be noticable. not to mention, over time carbon buildup could keep the valves slightly open as well.
of course this is just mindless banter over a specific motor that wont lead anywhere, but it keeps things interesting.
