Building LSX Hybrid SBC

Looking for a set of heads that will support 750-800 n/a. I see the l92 can flow 365 ported(advanced inductions says so) Are there any other options out there? I am building a carbed,14:1cr, around .750 solid roller cam, 434 ci. As always, a 300-400 shot will be added too.

I know of tfs,dart, and afr but I want to know real world flow numbers, if anyone has experience with these.

Thx
