I see Silvolite makes pistons for the 292 as well. Not 9+ compression like ross, but two (8.0:1 and 7.2:1) compression options and various overbore options, and thicker rings. I am still unsure why ross rings need to have a special honing procedure for them to work in the bore, perhaps someone can elaborate on that subject. This not being a racing engine, I wonder if ross was maybe too much piston for my intended purpose?
