Port heads or upgrade induction?
Port heads or upgrade induction? Can't do both at the moment. Which option would give bigger gains? Port my 243's, or switch to a fast 92/92 with an FTP lid and 85mm maf? Other mods are in my sig.

Heads without a doubt. We offer cnc porting to stage for $750, or you can get them setup with stainless valves in a size of your choice for $200 additional. 
That will include cnc machining, cnc valve job, decking & reassembly to match your camshaft.
Typical gains are 40-45rwhp over stock LS1 castings.
