Hey Karl, please read post #6 then look at the rough cast on the tops of the new pistons.

Doing a clean up cut on the top of the pistons will help a little, but I do not think that it is absolutely critical... I don't see much sharp edges that can become hot spots... That little bit of 'porosity' shouldn't hurt it...
