[TR] Lead substitutes

[Frank Fisher]

 i use unleaded gas in my stock TR3 head.for the miles i put on the car on occasional weekends i don't think i will have big problems.10 years of driving that way have been ok.and my other thought is, if i need to re-do the valves pulling the head is easy.

 What’s the wisdom on using lead substitute in gas for triumph four cylinder without modifications for unleaded head.  Use, don’t use?  I use the Valvoline racing oil with zinc in the engine.
Thanks,
