I was looking at the AA site and saw they carry 77mm 40hp piston and cylinder sets that slip into 1600 cases without rubber o-rings. Anyone tried these?

Those are the latest generation that have the larger fins on the cylinders, 90mm case size, but retained the alternative ring land dimensions. 2.0 vs 2.5 mm in width and slightly lower on the piston placement.
