I recommend to remove the cylindre also to check the piston rings.
Be careful, that no pieces of broken rings drop in your engine.

Baruch,

When you initially put the heads in did you put any "gasket goo", did you tork the head bolts to spec and or properly and were the head mating surfaces checked for warping?. It could be that the goo you used was not proper and combined with uneven tork and mismatched mating surfaces between head and cylinders that the goo melted/burnt and enhanced the gasket disintegration.
