If you dont raise the compression, you doenst need 100LL.

100LL is safe to about 165lbs static comp, so i "guess" 22-23cc can get you there.

What's the static compression with your 24cc?? About 140???

My tuner said with a higher timing the 100LL would work just fine with these domes. Given my squish .050", I'll be okay but I think it would be safer to run smaller domes right?

I was running my 421 Serval on 21cc Domes, 0.055" squish, a 1:1 ratio of 91 and 100ll, and using curve 3 on a Dynatek, which is 15* at 10-12K rpm (similar to +6).  Elevation 1500ft.  Didn't have any deto.  I forget what my static compression was, though.

Currently running 91 octane on 24cc domes, 0.045" squish and 13* at 10-12K (similar to +4)  I honestly haven't bothered checking comp on this setup. 

These setups used Shearer SBIF and PWK 35s. 

Hopefully this helps a little

0.050 is on the safe side for sure.

What is your static compression with 24cc???
