I don't know anyone that uses it.

Hi Rod.
Welcome to the forum. Sorry a little late to jump in with my experience. Let me straighten things out for you. In the good old US of A they have been using unleaded fuel since 1973-74. Therefore all engines during that era and after had cylinder heads fitted with hardened valve seats to compansate for the lack of lead in the fuel which helped cooling the valve seats. Since your car is a 1969 you would have to use the lead substitute otherwise you would risk of burning valve seats.
HOWEVER....... You are running late model Edelbrock alloy heads which I have been using on nearly every engine I built for the last 10 years due to their superior design and value for money. They are all fitted with hardened seats and stainless valves so you can virtually run any fuel as long as your compression ratio allows. To be on the safe side though I strongly recommend minimum 95 since better quality and cleaner fuel.
I hope this helps.

Cheers, Chris.

Hi Chris,

Thanks for taking the time to explain things for me. I didn't know that in the US they started using unleaded fuel back in the early to mid '70's, I'll have to remember if I buy another American car.   At least I now know that the alloy heads in my car do have hardened seats.

Anyway I have been using 98 fuel with the additive but today I topped her up with out the additive, I'm hoping she will run a little smoother and leaner as thebirdman68 stated but I guess that will probably take at least another fill to get rid of most of the valve saver fluid from the system.

Cheers
Rod
