Finishing up BBC build quench and dynamic compression questions

This is why you cc the heads chambers. Piston manufactures give you the piston head volume on their website. Example: Flat top pistons 5cc, D-dished pistons 18cc, domed pistons -20cc. The valve reliefs are included in these measurements. Fel-Pro gives you the compressed thickness, gasket bore volume. Your machinist can give you the finished bore of the cylinders. You must mock up the engine to get the deck clearance. There are formulas for calculating cylinder volume but if you grind on the top of the block for unshrouding a valve you would have to actually measure the cylinder for the volume. These calculators are more or less a guide.
