Lead replacement additive

[Westy Pre-Lit]

I have recently bought a 1967 Dodge Monaco with a 383 engine and was wondering what everybody else does regarding the use of lead replacement additive for cars of this age.

A few of my friends who have similar aged cars say they have never bothered with it but it worries me I could cause damage if I don't.

This is what I have put in a few times so far.

Should I carry on using it ?

Thanks for the reply aeropilot , I don't really have much history on the car but the log book shows it was imported in 2001.

Been trying to find out as much as I can about it and its all a bit confusing really. I think I'll play on the safe side and carry on putting it in at the moment until I need to take the heads off.

Then again I don't think the fuel stays in the car long enough to touch the sides of anything to cause a problem
