I take a brass hammer and smack it forwards and backwards a few times. Then I torque all my main caps to 25 foot pounds and I throw my dial indicator on to check my clearance.
Hey before you go to far check your oil pump drive into the bronze bushing to make sure it fits good. And put a 1/4 inch rod down through the top oil pressure hole to double check to make sure the 9/16 plug was installed under the rear main cap. Easy to fix now, hard job later. Measurement from top of block to plug should be 7 1/2-7 9/16 inches.
