Yes but you have to take the head off, so as far as it goes you may as well do the head and valves as well
Its a ongoing thing really if you intend to do the rings, get the whole lot and spend a while to overhaul the lot,
Piston rings, check pistons
Crankshaft shells, check the wear and replace if in doubt
De glaze the bores, check wear, and any marks
Remove, clean check valves and seats, regrind if necessary, and fit new oil seals
Thats the basics but look round and see what you can see
