I’m looking for a piston and cylinder set for an 056 Mag 2. Giving some thought to do an 056mag/066 hybrid. Let me know if you have one and a price.

There are aftermarket topends if you want.

I saw some on eBay. Any particular brand to look for or stay away from?

I can not answer you question.
I have seen those topends on Ebay, but not find any review of it.

If your looking for a performance gain don't bother with the AM big bore from a white box. Super long bar maybe but finding one with full plating is always the issue and short skirts. You need a DDawg piston anyway or NOS Stihl piston for a Mag11 build.
Wesco is the way and bore a jug. Just sayin if you plan to really use it.
I can test another big bore 660 next month if you like. This one has a good hole but needs ports fixed and the ring of death is right there now. Transfers are small but the casting was better than most. They normally got credited from the supplier and given away for hacking experience or experiments. Two survived a year at tree services. None went to production work... just no confidence in them generally.
