I’m all for using the 184 pistons with reworked stock heads.
But...... that’s quite a bit more involved of a project than bolting on a new set of heads.

And, unless the stock heads are in remarkably good condition....... you could easily spend almost as much(or more) prepping/refurbishing them than buying the budget friendly aftermarket alternatives.

Then, when it came time to tear into the shortblock you could just use flat top pistons instead.
