No effort needed -- just buy the off-the-shelf pistons

Peter Z has no flat-tops, at least none right now listed on his web page. In the past he usually had domed pistons but is now recommending Wiseco customs

Note that flat-tops make more power than stock dish-tops do, even when the compression is raised by decking the head. Decking the block works well if the pin-height is too low. Block decking also works to improve quench area -- but then so does a thinner (competition) head gasket
