The dome and skirt design hasn't changed, (despite my pleas to re-do it completely) the base forging has a little bit but it hasn't altered the weight significantly. A complete Wiseco 82mm assy. comes in around 390g. Stock Honda assy is in the range of 345-350. My lightweights are around 355g. The Wisecos will work ok out of the box and there are plenty running around out there just that way, but at +40g over stock it isn't doing your crank any favors.
