new to the forums and to 235 in general. I have a 53 chevy 210 PG car. got it running and runs well no odd noises. pulled the head to do some cleaning in the water jackets. So while I was in it I was doing a little inspecting and pulled the hyd lifters. Noticed the faced are pitted pretty bad on most and a few have chipped edges cam lobes look good smooth and clean. Planning on doing a rebuild towards the end of the yr. But I want to keep it going till then would it be better to replace them or just keep the orginals in there for now. thanks
