Good advice thank you, Stefan.

I may even have too much material on the 85A for modern fuel as the engine has had very little use. I plan to get the chosen head fully tested. I assume I will need new exhaust valves for unleaded fuel. What is the thinking on the valve seats? Were the originals good enough even if re-surfaced?
