Wayne, if you are sure that you are using a compatible driver then make sure the hammer you are using is heavy enough for the task. Not saying you are one of them but some folks fail to match the hammer weight to the job at hand. too light of a hammer will require a harder blow and make the guides feel like they are seized when they are actually just a standard .002+/- press fit. Drive each one down halfway and break it off with a chisel then drive the other half out. Stash the new guides in the freezer or on dry ice before installing and they will drive in much easier. You will need to use some sort of depth gauge to insure that you are installing them at the correct level as the guides you removed.

Rusty is correct in that the method he suggested is one way to remove valve guides in some engines but you have to use a sleeve that is at least the same length as the guide itself and slightly larger in inside diameter so that the O.D. of the guide will pull through the sleeve. This method may or may not work on the 327 but takes longer.
