Default YS/Saito 20/20 in OS 46FX

I have an OS 46FX that I'm currently running 30% Heli fuel in. I've added two head gaskets to prevent detonation in the engine and it runs great. I recently moved and I'm about to run out of the 30% Heli fuel and the max nitro the LHS carries is PowerMaster YS/Saito 20/20. Should I remove the head gaskets I added to the engine to run this fuel or what should I do to get the most power out of it?

You can only try and see. The 20/20 fuel has lower nitro, but more oil. More oil makes the engine "see" a slightly-higher compression ratio. If the engine run well as you now have it, leave it as-is. Otherwise, try with one extra gasket. Then with just the regular gasket.

We don't have a "sure" answer. It all depends upon conditions and the particular engine.
