Have an old friend of mine that questioned me about a couple of rocker arms on his 235' 6cyl. He really doesn't have a lot of money and wanted to know if he could just polish the rocker arm where it meets the valve? Myself personally, it looks to me some of these rockers might need a little heavier grind prior to the polishing. What type of tool would you use to take down that material a little bit before a polishing? I gently ran a small file over them and those rockers seem to be mighty hard. Thank you..
