Conway, All (most ?) engine builders use the NHRA spec sheet. Here it is for the 5.7 Hemi.
H.P. Disp. Deck Cl. Piston Height Vol Valves Cam Lift Springs Gasket

305 345 .000 Dome .210 16.4cc 2100/1600 602/569 Beehive .026

Even factory pistons can be manipulated, hence the nhra spec for dome height. There have been many DQs because the oem part did not meet the nhra specs. Ask Charlie Bob or me.lol Was Bales within spec for dome height? If he was, he is good. If he wasn't, he is out. About as black and white as you can get. Just my 2 cents worth. Keith Lynch 5035
