As far as I know, studies show lack of lead only hurts long idling fleet engines. Many times a machine shop just wants to make extra money inserting hardened valve seats. Additive sellers just want to sell additive. It might depend on the make too, some use cheaper iron than others. I dunno how alcohol affects that though. You might need head work to raise the compression for alcohol, or find a different head with a smaller volume. This is what I'll do with my '69 amc 232. I have a 65 head with smaller chambers.
