Honestly though, I do not have a lot of experience with cams but mine does not have a lot of valvetrain noise. It's louder than stock but it does not bother me at all. Whether it's more quiet than other cams I can't say. As far as the performance of the cam, I'm glad that I did not go any larger or smaller. It seems to be a good in-between cam without sacrificing much on either end. If you have any questions OP, feel free to ask.

That would make yours bump a little more @ idle but because of the carb it
may also dirty the plugs sitting at a long stoplight. I think CAMAROZ's cam
would sound great with yours having 18 more cubes and almost 10.9 comp.
Not that your current combo isn't great but you have enough stall and gear to maybe shift your powerband 500 rpm north and not lose any of its street
friendly manners.

I thought I would throw this into the mix. These are new cams by Lunati just for carbed LS set ups:
LS1 WITH CARB
60519** 2400 - 6800 CAMSHAFT, GM LS VHRX278-08CX 278/282 227/231 .651/.651 108/108
60520** 2800 - 7000 CAMSHAFT, GM LS VHRX286-08CX 286/294 235/243 .651/.651 108/108
60521** 3200 - 7200 CAMSHAFT, GM LS VHRX298-08CX 298/306 247/255 .651/.651 108/108
60522** 3600 - 7500 CAMSHAFT, GM LS VHRX306-08CX 306/314 255/263 .651/.651 108/108

I have noticed the that valvetrains in these cars that run a true roller rocker tend to be quieter than OEM rockers. If it has a tick you most likely have a setup or mechanical issue but with a more aggressive higher lift cam and the springs required for it the sewing machine noise is to be expected. Also I think some people just have more sensitivity and less tolerance for it (which may be your case???)....

I have completed my build and it is a great success. I just wish I had more lope in the idle. So, I am considering putting in a new, larger cam profile. I have a pretty good idea, what I would design, but I thought it would be fun if everyone said what they thought would be ideal. I have already sent Patrick G $25 bux, so when he is done, we can compare what we all came up with to what he suggests. Fun stuff.
Parameters:
The cam must utilize my existing PAC 1518 beehive springs.
I will be shifting no higher than 6500 RPM.
The cam must have enough vacuum to run my power brakes.
I want to maximize power, but I don't want to beat the hell out of my springs. I drive my car a lot.
I will not be changing my torque converter or rear gear.
Here is the set up.
1965 Skylark - 3500 lbs.
LQ9 with PRC Stage 1 CNC LS6 heads
10.88:1 compression
Performer RPM intake
Holley/Pro-Systems 780 CFM HP series carburetor
MSD 6010 ingition
Current Camshaft - 222/224 .566/.568 112 lobe separation on 110 Intake Center Line
Th200-4R transmission
3000 RPM Circle D converter
3.90 rear gear
28" tall tire
I will go first. I am thinking a Torquer V2 with a 110 lobe separation would be perfect. So: 232/234 .596/.598 on 110.
Here is a picture of the subject.

This dyno sheet is very interesting. It compares a F13 (230/232) cam to a 224 cam on the dyno. The f13 gives up very little down low for a 26 HP gain up top.
Here is the thread where I stole this graph:

Here is another graph from Texas speed that really breaks down the little cams:

I dunno about that dyno graph but I have ridden in a F13 cammed car and it was a complete dog in the bottom end (under 5k). I understand FMS comes with a good reputation but that's one of the reasons I never recommend them...my own personal experience.
