If you have the press fit valves you do have to grip them and twist them out , some leather wrapped around them could protect them from getting marred up .

Are we speaking about oil line check valves or SRIS check valves? If it's the SRIS valves, then Dave's solution is correct. Twisting them with a spanner will break the taper loose. If we are talking oil line check valves, they are not removable. Oh you can get them off OK, but never get them back on.
I was born with nothing and still have most of it left.
