Hi, you may have read my previous posts about my slightly smoking 2wd saph. I decided to replace the steam seals myself. so far all has gone well, ive cleaned up all the valves and grinded them in and the head now looks new. The seals are getting fitted on Saturday and im hoping to put everything back together by sunday PM. The only thing is im now thinking should i do the piston rings too? There is no play in the pistons in the block but the car has covered 160k and this is the first rebuild it has has as far as i know. What do you think i should do.

BTW im fitting a GRP a head gasket and a cosmetic rocker cover gasket.
