the noise came back with a vengeance, whatever the issue was... it broke my valve cover.

Front of cover? Did you replace the tensioners when you did the chain?
I did a bone head move years ago where I didn’t install the cam sprocket spacer. Oops.
It was trouble free all day including three hour round trip to the dyno, dyno time at 20 psi boost, and ran errands all afternoon.
Two miles from home and zero warning, snapped the cam sprocket in three pieces, imploded the tensioner, and sent all the shrapnel into the oil pan.. I had it all back up and running to perfection three days later and heading to the Louisville meet.
Mistakes happen.

yeah, I had bought the timing kit from adtr.net so everything is new
so a bit more of an update, it was the drivers side exhaust
camshaft bolt. it completely sheared off and broke the valve cover.
it also broke the camshaft position sensor and both the head of the bolt and the plastic of the camshaft position sensor are somewhere in my oil pan probably.
I have to fish it out somehow, I'm probably gonna take the timing cover off, remove the remaining piece of the camshaft bolt from the camshaft, replace it with an ARP bolt i bought and fish out the bolt with a magnet and hopefully the plastic with something I can scrape it with if it doesn't come out when I change the oil.
not sure exactly why it sounded the way it did but there was something moving there.
luckily the timing sprocket is still there and in position, I'm pretty sure timing is still good so there was not a lot of damage other than the valve cover and camshaft position sensor. there are some scuffs and scratches here and there but nothing that would affect the performance of the car or on any mating surface.
I pray that this is it and im finally able to drive my car once again.

Wow, quite the mess. I fished all mine out the front of the pan with the timing cover off. Lots of brake clean to wash any remainder towards the plug.
I forgot to mention the five brand new stainless valves that I also bent..
I ended making a clock out of the nuked parts on that car.
Keep us updated!

Sounds like the cam sprocket bolt came loose. That's probably when the noise started. Then after running loose it broke. My guess is a TTY bolt was reused?
You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference
I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

that was my guess too, however I wouldn't know if it was since i bought the head already assembled with the cams on. I replaced the hydraulic lash adjusters or lifters and the rockers but the cams were still on, didn't touch them.
I haven't had a lot of time on my hand so I haven't been able to do much but i have taken the timing cover off and found the plastic piece from the camshaft position sensor, however I haven't found the camshaft bolt yet. I got a magnet that bends so hopefully with some luck ill be able to fish it out fairly quickly. the only thing left to do after that is remove what's left of the bolt, replace it and seal everything back up.
