Hey guys just got my head resurfaced on a long 460 and now my push rods are too long. Any advice? I've heard of this happening before but never experienced it personally and it's VERY time sensitive to getting it back running thanks.
I agree with TX Jim's response. Something doesn't make sense. If head milled to bring into a planar surface to correct for warpage then MAX I would expect to see removed is 0.100 and more likely 0.050 ( 50 thousandths).
Are you sure you got back the head you sent in?
The volume contained within the head, for a diesel, is usually quit small. Removing significant amounts of thickness of the head changes many things: Reduces volume, raises compression, puts valves closes to piston, changes swirl within the space, and could place a sharp edge inside the circumference of the cylinder leading to hot spots.
