It couldn't have worked out better. The new set of lifters are from the same company, same part number, but they are different from the ones in the engine.

The new lifter is on the left. On that one the piece with the pushrod cup covers the top of the piston, on the other one it goes inside the piston. There are other differences inside. I didn't take photos of that because I got disgusted and just put it back together.

In that photo the new one is on the right. It's shorter so now I'm probably in need of a longer set of pushrods.
I bought the same brand of lifters trying to avoid exactly that.
Madness.
