Flat top vs dish I am getting ready to purchase a rotating assembly, and my intentions are N/A now, boost later. I am on the fence about piston selection. I was leaning towards dishes pistons with small chamber heads to keep compression up and just swapping heads later. Is there a performance loss with dish vs flat top if the compression is the same? And if any sponsors or anyone has a deal on a rotating assembly, I am interested. It's for a 4 inch bore dart ls shp block. 4 inch stroke and 4.065-4.070 pistons. 6.125 rod.

Keeping compression constant and varying dish/dome and combustion chamber will also have an effect, but will be much more nuanced...
