I tore into my 383 sbc and discovered a few things and would like your opinions. First some of the roller rocker arms were making contact with spring/retainer and now the aluminum rockers have a small divot in them. Can I smooth these out with a dremel and reuse them? The divots are maybe 1/16th deep and again not on all of the rockers, I believe the contact probably was made when I had it wound tight 5500 plus??? Two can you reuse the rocker arm nuts/polylocks? Engine has less than 6500 miles on it. Has anyone heard of Engine Works products are they china stuff? Probably will have more questions this week so thanks for the help.
