TR6 Gasoline

["Keith Graves" <KGraves@talx.com>]

I just purchased a 1974 TR6 and have a basic question.  What kind of gas
should I use.  I assume it was intended to use regular, the manual
indicates an octane of at least 99.  The best unleaded around me is only
92.  

Should I add an octane booster?  Or I've also seen a releading solution.

Also, is there a way to tell if the engine has been altered to accept
unleaded?

Thanks for the help.
