Today I assembled the 455 that's going into Glenn, and BJ's old GMC. And I found 3 of the steel rocker arm pivots bent. This condition caused the push rods to be damaged because the push rods were in contact with the cast iron heads. So I installed the stock aluminum ones from the downer 455. I just don't see how the pivot's got bent. Any ideas?Bob Dunahugh
