Honestly, I don't like anything over 15. That's just me. I've hit 50 before and hear no sign of pinging or detonation at all.
So fellas I need some new cams. I hear great things about JWT but I'm unsure which ones to get. Tax Season is stupid good to me this year. So I am upgrading a lot before finally heading back to the dyno for a better tune.
Heres a basic layout of my current mods
Apexi PFC D-Jetro W/Commander
Built bottom end SR20
Bone stock head
ISIS intake manifold
Tial MV-S 38mm wastegate
GT2871R .64
Currently running a rather large GReddy FMIC but i am switching to the PBM HMIC
Nismo 740cc injectors in a CS Fuel rail powered by a walbro 255
I may be missing something. But this is what I am getting before going back to the dyno-
Apexi AVCR
Competition Stage 4 clutch/flywheel
PBM HMIC with recirc'd BOV
New Apexi headgasket
ARP studs
Possible water/meth injection
And then the cams.
My ultimate goal is 400whp on pump.
Would S3 cams be good? Or a little overkill?

With the setup you want to run S3 cams sounds good, however like I stated above when doing cams don't forget to do the valves and valve springs the stock ones are not made to handle aftermarket cams due to their spring rate
Also meth system is too complex for the power goals you're trying to reach stay away from that but everything else sounds good
Also if you're thinking of taking out the head to do the headgasket might as well as overhaul the top end and get new valves and do a 3 or 5 angle valve job or get it machined and balanced properly for durability
just my opinion of what I would do if I had your setup right now
