pistion head volume

[o1heavy]

selecting pistions for my 360

what is pistion volume

sorry if this a silly question
thanks for ur help

 

[70aarcuda]

can be the volume of the dome if it has a dome..

or can be the volume of the valve reliefs...

Are you looking at a specific piston?

found out it means how the pistion dome or lack of dome effects the combustion chamber
