Something decent to start with. You may want to check the engine number just behind the distributor to see if it is a full pressure engine. The 56 had perimeter valve cover screws and looks like yours has center of the cover studs. Could be any earlier engine but if it's good run it but maybe a bit more gently than a full pressure unit. If you post the engine number there are ones here that are whizzes at deciphering them.
