What do you mean doesn't brake as good?

Do you have any vacuum for the booster to actually work?

What isn't normal? Pedal effort? Noise? Vibration? Sponginess?

You are losing power brakes. Some to all....

You could have a leak, or the cam might be too big (I'm not really into cams) to provide good vacuum to the booster.

If you had no issue before, but do now, it's related to the can swap. Either a line that isn't sealing right, is off, or it's the cam itself. It's easy to check for a leak with a bottle of propane.... run it around and if there is a leak the propane will get sucked in and the idle will rise.
