Ok this is what I ran into with 440-1 heads. Standard (zero) offset roller lifters worked with my stock blocks (3/3 pushrods) but when back in 2008-2009 I had to buy a set of offset lifters for clearance on my Keith Black block. The shortblock was built and I didn’t want to tear it apart to grind clearance. When I tore it apart the next time I did some valley grinding so this would no longer be an issue. Some of these bigger pushrods cause some clearance issues.
