eta combustion chambers are "bathtub" shaped, not hemispherical. And many aftermarket pistons aren't very good..
I'm pretty sure the 89.6mm crank clears no problem. you may have to shave the intermediate shaft, but there aren't normally block issues. the M52 crank counterweights being larger is why there are more clearance issues in general (even if you don't use the 130mm rod/i piston combo).
also pretty sure the OP said it already fits and clears no problem.
