Looking for first chevelle

[txchevelle35]

Hi All,

I've been using this forum for the last few months researching my first Chevelle purchase. Looking for a 68-69 hard top coupe.

There's a lot of knowledgable people on here so I was hoping someone could help with a few questions I've run into.

Since Chevelles were built in the 60s, they had to use Leaded gasoline. I heard that since the only gas availble now is unleaded, using unleaded will damage the engine unless certain valves are replaced. What valves need to be replaced? Can an classic car inspector verify that the valves in a Chevelle are up to date and can use unleaded gas?


Thanks for any assistance ya'll can provide
