Yes. I like to run at least 10.5:1 compression with the old style chamber.
Like was mentioned before, it needs to work with the rest of the build. Could 10.5:1 be too much? If a guy is going to run his cam advanced and ALL his timing in by 2,000 rpm, even with more compression... well, who knows? With enough compression you don't need the band aids.
Running more compression is worth it if you know how to take advantage of it.
disclaimer; guys on the west coast say their gas is garbage... I defer to those guys for west coasters.
