I have a A65 that I'm collecting parts for to overhaul as experimental. Already own a set of NFS 8:1 pistons that had a lightening program run on them so they match the weight of the original cast pistons. The engine is going to be limited to 2600 rpm(A75) as I figure that's a safe limit. Question, what valve seats and exhaust valves should I be using to avoid any issues regardless of what fuel gets used. I have good access to ethanol free mogas but may also need to burn 100LL. Coments? Suggestions?
