Gary I don't know if this finding might help you but look up Diamond pistons they have a 1.30 CH, Diamond says it's better suited foe the 4.25 crank because it puts piston 10 thou below deck so if you have to correct deck height to square it it will bring it to or close to zero. Check it out it might be what you need.
