Valvetrain Noise
After any of you did a cam swap, was your valvetrain noiser than before? Mine specifically sounds maybe like I have a weak lifter, it has that loose sort of soft tapping noise that the old SBC's made when they weren't adjusted right. It never made that noise before and I double checked the rockers after about 100 miles and they are all tight.

You have the sewing machine effect. Big cam=louder valvetrain.

I have it too. If there's any way to make it quieter, I'd love to know.

You can upgrade your rockers to quite it but it isn't really needed. Try Yella Terras, they work for quiting the valvetrain.
