Pi x R squared equals the piston area for fiquring the lifting pressure -------example--------a 4 inch bore size would be R = 2------ soooo 2 x2 x 3.14 = 1256 x 100 psi = 125600 lbs total force------
The aluminum heads -the washers under the nuts have squeased the alum head material into the threaded area of the stud which will keep the head tight against the block----There are step washers available that do require clearancing but will prevent that------
