TRW L2249N Pistons: Info on them and do they fit roller blocks?

Hey guys,
A couple of people have a set of old TRW L2249N pistons that i m looking at. i m having a hardtime finding info on these units and wondering if they will fit a stock deck height fox roller motor correctly. I m looking to build a pump gas compression motor 306 NA.

Also, are they press fit pins, etc? Dome size?

IIRC these are an old set of pop-ups. I used them in an 85' roller block around 20 years ago so they should work just fine. pretty sure the dome was 9cc and i remember them being floating pins but i could be wrong about that.Should be around 10.5:1 with 60cc heads and about .010 in the hole
