Several problems with PEH's thinking...
All cars are different. He does not know what settings that indy used....and neither do you... We don't know how often or well you change oil, etc... If you ever have the valve train apart...like to install valve stem seals.... it is recommended to put new adjusting nuts and lock nuts on.... and rotators also... small things can dramatically lengthen the service life of your engine...and the ease of maintenance...
Is it really worth taking a chance on burning an exhaust valve... rather than getting your "_____ " in gear and acquiring the tools and knowledge to do it yourself ?
