Drilling the galley was a slow and nerve racking experience for me. Peening the tube down right made my butthole pucker. But it turned out just fine. My crossover tube is just to supply a small amount of oil to the lifters because I shut off the oil from leaving #1 main with set screw. I don’t trust “splash” oiling the lifters in a street engine.
