Piston and sleeve will fit.
Drum valve can be fitted but the inside of the crankcase need to be relieved for a fuel/air passage as the drum valve flows the mixture on a 45 degree angle upward, not straight into the rear of the crankshaft like the disk valve.
This can be done with a dremal tool. You need to match the passage on the new drum valve. I really need to put some pics of this in the FAQ section. Keep checking there.
