Camshaft @ Split Overlap Hi NX20, the camshaft you have chosen should be "timed" at Split Overlap, NOT RETARDED as you state.
This will time your IVCP at 44*
The Intake Valve Closing point would work better if on a 116-117 C/L.
To know your Timing Chain choice would help as most "Dual Rollers" stretch more than a Single with Dampener.
This "guess" of mine is NOT best as NO REPORT for intended use was provided.
"G" asked the best question, provide more information.
You could send the Lobe Files, then I could model using EAP.

I think that cam will be a decent street cam, BUT with those ramp rates you need some additional support in the valvevtrain.
Minimum get a set of psi 1511 springs. Better yet get AFR 8019.
Minimum get 5/16" x 0.080 pushrods. Better yet, get 11/32" x .105 pushrods.

4l80 going in with 3600 converter
Intend to spray 150ish on it as well.
This originally was to be a low buck build but then i got the heads and that changed things. SO:
Engine is iron 6.0
(Stock) short block.
New Cam bearings
fast 102 unported
1 7/8 headers Y pipe 3" single exhaust.
bought these heads
https://ls1tech.com/forums/parts-classifieds/1809543-ls-afr-215-s-hand-finished-tony-mamo.html
Johnson short travel Lifters
11/32 push rods
yella terra
The engine is sitting on a stand.
currently has tick cam
231 238 .617 .598 113lsa
don't have all the specs in front of me at the moment. Was thinking of changing cams.

That 224/230, 114* will work great in a street/strip car & 150 shot
with the MAMOFIED AFR 215s. +3* advance would be ideal IMO
some will say the cam is little small but that combo will RIP!
Lift on cam is good also with those heads.
Your single 3" after Y will cost some power.

Actually the Tick cam would work even better in the 6.0
with the AFR heads & N2O, sell the new cam with the LS1,
LOL Exhaust will really hold it back now!

I have a Comp Cam with similar specs in my 68 Camaro LS-1 swap. I am at 223/231 .610/.617. The cam was ground with a 112 lobe separation angle and a107 degree intake centerline, but I retarded it 4 degrees to get a better PTV clearance. The RPM ranges is stated as 1700-6800 RPM and I made 400 RWHP at about 6000 RPM. My max torque is 383 and I make 350+ Ftlbs from 3400-6000 RPM. Idles at 800 RPM with 16" of vacuum. Great street/strip cam in my opinion
