I had the classic sewing machine noise at stock, it only got louder when I got rid of the cast iron manifolds

idk why anyone is talking about tearing your motor down to find what's causing some valvetrain noise that's pretty normal in all cars. It made valvetrain noise when I got it at 19K, and it still makes the same racket.
