You might want to check to see if the pushrod is contacting the intake manifold. The spot where the pushrod goes through the intake. I know it sounds silly but, if I recall, there was some discussion on this very topic a while back. It was determined that the pushrod was contacting the side of the hole in the manifold and putting lateral stress on the pushrod and consequently the lifter. The lifter failed and the cam lobe was trashed. Couldn't hurt to check.

Just my .02 worth
