Killed another cam, need to go roller, need recommendations

2 different engines; the last setup was caught in the beginnings of a couple lifters starting to gall up, so the pan was cleaned out and a couple of bearings were checked and it looked okay. Replaced the parts and made another go on the outer valve springs only with driven break in oil, plus the engine started almost immediately. I ran 20w50 valvoline VR1 after break in. I don’t think I have more than 100 miles on it… I wasn’t planning on tubing the block
