my car was having some power steering pump issues that were noisy and I recently fixed it and now I hear a weird tapping/ticking noise I am assuming is coming from the valve train, could anyone possibly someone who has used any of these parts tell me if I should be concerned I know dual valve springs change the noise of the valves opening and closing but this doesn’t sound normal to me. Thank you in advance also sorry theaudio Quality isn’t great The car is loud and it makes the mic freak out.

These are the videos

Hard to tell from the video if it's just normal noise or not.. with high lift cam and high capacity springs it will sound like there's 16 sewing machines running in the engine bay, lots of clicking.. But there shouldn't be any one singular tap that is more pronounced than the rest , like an exhaust leak or a piston slap or a single bad lifter would cause.
