To add to Dwight's post Head gaskets are measures (By Wesley) in all there places between the cylinder bores in the center.. then averaged for the final gasket thickness number. At EMC I was taught by Wesley to push the oil out of the rod bearing (push down on piston top) and bring the piston to TDC and measure the deck along the C/L of the wrist pin (front to back). Avg the numbers if they are different. I would bet all the methods he uses at EMC are what NHRA tech uses or should use. Good info on Dwights post. Been there done that, AYE!
