I did mean seats, and realized my error after the first answer came back.
This guy was negative about everything. My six year twins were actually
behaving so I could not break away from all the "sky is falling" stories
and about his rust problems on his Mercury Parklane - so in a sense he's a
F*rd guy and it showed.
Thanks for the info everyone!

Please respond to The
Chevelle Mailing List
I wouldn?t worry much about the holes in the pistons that could be
caused by detonation because of low octane, I don?t think that can
happen because of lead. From what I have been reached the only thing
that could happen are burned valve seats but I do agree on your theory
about the heat cycles hardening the material.
And I think you mean hardened seats, not hardened guides right ??
I'd just drive it as is until the rebuild
Full Revs!!!

Subject: [Chevelle-list] Fuel / Lead additives
I guy asked me what fuel I used in my '66 Chevelle (stock 396 with mild
cam) while we were waiting for our step off time in the local July 4th
Parade. I told him regular 89 octane right now, but have used 91 and 93
octane and noticed now real difference in how the car ran. He got all
over
me for not using a "lead additive". I told him I am under the theory
that
the engine has been heated up and cold down so many times over the years
that the valve guides are hardened by now (I do plan on rebuilding the
engine with hardened guides in a few years when doing my restoration).
His
point was that without having a lead additive that damage would be
caused
to the pistons by blowing holes in them if the car back fires or pings
especially under hard acceleration. My hardly occasional back fire
comes
through my carb and the car is timed that it never ping's. I do get an
occasional engine run on for a half a second which I could blame on the
lower octane. Any one using "lead additive" and any thoughts supporting
this guys comments?
Thanks,
