Magnum camshaft questions

OK I'm up to date on crate engines -carb-manual pump
my question here is how much lift will the stock rockers take?
not that op askeed
I think aj is correct about more duration
depending on if op wants to keep his current torque curve or move it up
I just checked Mike Jones HR webpage and he shows 276, 280, 284 @.006 with 576 lift
ought to pump up a 9:1 motor
anyone know what that cam is at .006?
whats your cranking compression ?
