The Wasser crank will not fit in the TypeIV, there is no way possible...
The Wassers did have some head sealing problems, due to people running conventional coolants, and this erroding the sealing surface.
You must run the factory "blue" coolant from V.W.
A properly built and maintained Wasser will outlive a Type IV 2 to one....
The piston were designed to promote "swirl" and to keep the combustion in the piston, to transfer the heat energy to the coolant system.
Now we're starting to see piston designs like the Super Squishy from ACNet that are "revolutionary in design" Hmmm, I wonder who had this Idea first.
The V.W. engineers where not dumb when they designed this motor, and alot of problems in past designs where changed in this model.
