As long as the rockers are smooth, you'll be okay.

As long as the stock coil springs don't bind with the new cam they should be ok too I think. If you are adding a lot of lift, you might need to get new springs to match it. Also I've read that if the camshaft is a regrind, or an all new aftermarket cam with different than stock base circle on the lobes, you might need to buy lash pads to get the proper valve adjustment.
