Oiling vs non oiling pushrod

I had oil through push rods on in my motor Ball&Ball style with T&D rockers. 800 miles tore the motor down after an accident. All 8 intake push rods were gulled. I never had this problem with non-oil push rods, I ordered a new set of cranes . Ball&Ball. The ends seam soft. and the intake push rods are at a hard angle
