I've noticed many vendors are concentrating on the NA and N20 applications but what about the guys that want a larger combustion chamber/low CR for a sick and cheap FI setup?

seems like to me most everyone in FI is using the AFR 225's...

if im leaving a head out that would be good for FI please inform me.

Yeap any CNC ported,stage 2 or 3 LS6 style LQ9/LQ4 head, without welded chambers.

are they thick enought to hold down under 14+ lbs of boost?

The ETs have a thick deck on them.

You don't need thick deck for 14lbs of boost. You need studs and good block/head deck prep with a nice set of Cometics.
14lbs of boost is peanuts.

notice i said +.... 14 would be a good after about 2-3 weeks at 10... I'd like to see upwards of 20.....

i checked TEA's stuff and there 6.0/ls6 stuff is just as much as or close to the price of AFR 225?

are you seeing a different vendor out there?
no PP quotes please... not knocking but there have been issues and i understand people over come them but i want some more assurance before i drop 1200+ on a peice of metal

Yeap, if you're heading 20+ lbs boost then thicker deck is the way to go.
