Hey Brent,
I had a similar problem where I kept breaking push rods and it turned out to be a tolerance problem with the intake manifold. I also noticed scratches on the under side of the rocker. When everything was put back together the adjustment tip on the rockers broke. Also all the needle berings in the lifter were gone and on one lifter the side wall was cracked.
Be careful my builder left the bad lifter in. I've got a story better than yours. ... Make sure the builder checks the lifters and the rocker adjustment stud.
