Don’t even think that noise is related to belt, not sure what that is yet

shouldn't really be hearing any new sounds, the thicker factory cast manifolds do a better job of silencing the engine, with the thinner longtubes the noise from the valvetrain is louder, thats about it
That chirping sound drives me nuts, not sure what that is, any ideas?

Who did your trunion upgrade install? Were the rockers soaked in oil and smooth as opposed to gritty feeling after install? I had a few rockers that weren't as smooth as others and I soaked them in oil overnight and they were much better... I don't think the noise you are hearing is anything to be concerned about. Just normal valve train noise you get with a CAM, mine has a pretty similar sound.
Had the machine shop do the trunion upgrade. I believe they soaked them up, as they were moving very smoothly before we installed them. That noise drives me nuts because sounds bit like a belt.
