Hi Tom,
I switched to unleaded and had "vanishing lash" from seat
recession in a 914-6 daily driver (aluminum heads with ferrous
seats--not stellite though). Was measurable on two valve lash
adjustments over about 12,000 miles (when we pulled the heads). Had
the heads reworked with hardened valve seats--then no problem.
Agree though that cast iron heads and hydraulic lifters should
help minimize the problem.
Cam grind is also a player along with spring tension.

I use a lead substitute in my `66 Elky on occasion. Why not just use
that?

There was an article in one of the car magazines a while back that
showed the increase was greater in low octane fuel than high octane
fuel. It showed that costwise you were better off buying higher
octane gas than the booster...
