Yes the 064 piston is taller and has a longer skirt. You have to machine a pop up on the piston and shorten the skirt. The channel for the connecting rod is too narrow for a husqvarna and needs to be opened up.
Machining the cylinder can be a pain in the @@@. Its possible but it can lead to complications. I recommend machining the piston, much easier.
Big bore cylinders have a ring on the top of the cylinder wall where the nikasil plating is dented and rough possibly snagging a ring. It is a very small band and can be seen using a dental mirror. It is very evident when you cut the head off for a 2-piece.
Snagging a ring is what I meant by ring run out.
