I have a question... just bought a preowned ported 102 for my LS2...
I have a LS2 ported tb and Airaid. I have a 224/230 cam and 1 3/4 ARH making 421/419 rw via Mustang Dyno.
I know i can leave these but should I upgrade the tb to a 102mm or a ported Z tb? If i do that would i need a new maf, cai, injectors and 1 7/8 headers?

Your combo is fine as it sits. None of the upgrades you suggest will make any meaningful gains. As to header size, my friend runs a 2200hp car that hit high 6's and he runs 1 7/8 headers. By the way, he ran that at high altitude. 1 3/4 is fine for any street application.
