Back in the day when they took lead out of gas there was a lot of concern that without the cushioning effect the lead had on the valve face there would be bent and broken valves. Since my car fits those criteria and will be driving soon what if any concerns should I be aware of?? Fairly technical but Thanks for any help that might save me a damaged engine. Best to Ya

So this is a very interesting topic....would putting lead additive into a '73 2.0 gas tank help with anything? Improve anything? Add some extra cushion of comfort for anything?
Thank you all very much! gg |
