How loud is your heads and cam car?

Mine was loud with the old cam on XE lobes but not loud enough I could hear it when driving around.
Once I added stock style foam under the Fast intake and went to an EPS cam it is now just as quiet as my 5.3 truck (stock).
Does make a lot of hissing noise especially on cold start up though.

The 228 and 232 lobes are XER lobes most likely which is why they give off that sewing machine sound.
Those lobes were originally designed for SBC applications and have been branched over to the LS platform.
Aside from the noise they make I prefer the newer lobes that are much quieter and offer a better package all around for the ls valve train. I have a cam that is a lot bigger than yours(239/247 110lsa) and it makes no valve train noise with the lobes I have(LSL intake and exhaust).

Same ETP 5.3 heads with both cams.

While I didn't have heads on the car, I had MS3 cam. here's a couple of vids, in all of these vids I had Pacesetter LTs, TSP ORY, 3" Magnaflow bullet, dumped.

If you want a good lobe that is specific for the LS motor and is less aggressive than the LSL lobes the LXL lobes are for you. If you want a slightly less aggressive lobe than the LXL lobe then HUC lobes would be my next recommendation.

you guys hear that hum/rubbing noise from :26-:29 seconds? I just did a head/cam/intake etc swap and I have that same noise and I guess I dont recognize if thats normal with the swap or not. To me it has me worried that its a cam bearing and I just cant pinpoint the noise. But maybe its just normal and im paranoid right now. My cam bearing looked good though... maybe slight copper color but it was very minimal and the factory cam that I pulled out all of the surfaces were like brand new! what do you guys think?? I dont mean to hijack but the video posted was a good representation. VIDEO ON THE 1st PAGE
